Water levels across the state are still above average, but a small break from the recent heavy rains has allowed some area water bodies to stabilize a bit. This and breaks of brilliant sun in between the rough weather have brought out hikers and bikers, anglers and kayakers, bird watchers and butterfly spotters alike.

On the Winnebago system, Oshkosh DNR fisheries staff and a host of volunteers began the annual bottom trawling survey. The trawling assessment provides critical information on year class strength, population trends, and abundance of game and nongame fish species. Recent walleye catch on Winnebago is made up of adult fish between 15 and 18 inches. There are also good numbers of perch and crappie ranging from five to seven inches. Surveying will continue throughout the next few months. Angler report productive walleye fishing on Lake Winnebago as well as good perch fishing throughout the system.

The weather started to clear up just as last weekend rolled in, bringing out anglers and pleasure boaters alike. On Green Bay, anglers at the mouth of the Peshtigo were landing walleye, drum, catfish and small mouth; anglers on the Oconto were seeing much of the same, with some very large perch, middling walleye and rock bass added to the mix. The walleye bite has picked up some on the lower bay with angler off Suamico, Bayshore and Geano beach all finding a fairly consistent bite, with the majority of the boats bringing in three to four keeper walleyes.

Fishing pressure was high in Door County this past week due to a salmon tournament. Although it was a tough bite due to warm water conditions, chinook salmon and rainbow trout were being caught from Sturgeon Bay to Washington Island. A few anglers reported success with smallmouth bass around Egg Harbor. Yellow perch fishing has been fairly good with good numbers of fish being caught and fish up to 13 inches have been reported.

In southeast Lake Michigan harbors, anglers reported a mixed bag of coho and chinook being landed in addition to browns, lakers and rainbow trout. Alewives have moved farther down the water column and many anglers are using spoons. Many of the boaters in Ozaukee were there to participate in salmon derby. The majority of catches again went to trout and salmon. Those catching trout have been seeing success late and midday. Water temperatures on the surface have been right around 68 to 70 degrees.

Buck antler growth has almost ended and they'll begin to shed velvet in a month or so. Continue to keep an eye out for fawns at roadsides as this year's youngsters grow up and start to move more independently.

On marshland across the state, Canada geese are starting to flock and stage on oat, cut hay fields and other open areas. Turkey broods with poults of all sizes are being seen, indicating there has been some renesting. Other birds out in the open include pelicans, egrets and herons.

The mosquitos have backed off just a touch, but expect them in force wherever wet areas meet woods. Blueberries are just passed peak and will start to decline while blackberries are ripening. Prairie flowers are in bloom and close to peak in most areas, much to the delight of local butterfly and bee populations. Keep your eye out for monarchs in your area! Compass and cup plant, blazing star, purple coneflower and swamp milkweed are just a few of those blanketing the open spaces in between woods, field and stream."

Archery, birding, cooking, hunting and fishing are among the fun things to be taught by Department of Natural Resources staff and expert volunteers during the free and family-friendly August Horicon Marsh Outdoor Skills Day on August 5.

Brule River State Forest - A rare albino fawn was recently observed and photographed by a Douglas County resident near Dairyland, WI. Blueberries can still be found in good numbers but we are past the peak of their abundance and they will disappear quickly, it was an excellent year for both size and abundance this year. Hazel nuts, both American and beaked, are nearing the ripening stage are both very abundant this year. Blackberries are abundant but most are not yet ripened. - Greg Kessler, wildlife biologist

Park Falls DNR Service Center area

Flambeau River State Forest - Fishermen have been fishing the Flambeau River in hopes of catching musky, walleye, northerns and bass. There has been some very successful fishermen. Folks are really enjoying the river experience. The water levels are low in some spots on the river. Wild rice is ripening, goldenrod blooming, and night hawks migrating. Wild bergamot, bunch berries, blue cohosh, and blue bead lilies are blossoming. Blueberries, raspberries , and the soon ripe blackberries are abundant. Trees, shrubs , plants and forbs are healthy and flourishingThe Monarch butterflies seem to be more numerous this year. Horse flies, black flies and mosquitoes are out, so be prepared. Elk cow and calf groups are secretive and hanging out in cover. Elk calves are weaning off of the cows and eating more vegetation. Bulls are hanging out in bachelor groups constantly eating. The bulls are still in velvet. The first to lose their velvet is the raghorns. All velvet should be off by the end of August and bugling will commence. The weather forecast for the weekend, calls for Friday to have a 30 percent chance of rain with a high of 70 and a low of 50. Saturday should be mostly sunny with a slight chance of t-storms after 1 p.m. with a high of 73 and a low of 52, and Sunday, showers are likely with a high of 72 and a low of 51. There is a detour on the north end of the Flambeau Forest ATV/UTV Trail trail between Hwy E and Hwy 70. This detour is about 200 yards. There is heavy equipment working on the trail now, so use caution. - Diane Stowell, forestry technician advanced and visitor services associate

Northeast Region

Northern Lake Michigan fisheries team report

This report is for the week of July 23-29. Water levels were starting to return to normal this past week with most dam's in the area reducing their flows to only having partial gates open. With the steamy weather, pleasure boaters, tubers, and kayakers are out in full force.

Marinette County - Anglers below the dam at Peshtigo have been catching some panfish and the occasional trout on the Power House side of the river. Live bait and small plastics are being used. The mouth of the Peshtigo River and the holes up river has been producing walleye, perch, drum, catfish, and small mouth. Most anglers are using a simple jig and live bait or plastic. Brown trout were still being caught in the vicinity of the trout bar off the Little River Boat Launch. Anglers also report catching a few perch adjacent to weed beds in 9 to 11 feet of water. Boaters and shore anglers alike report an up tick in fishing success for walleye and small mouth on the Menominee River. Live bait fished on bottom by shore anglers are catching walleye, small mouth, drum, walleye, and cat fish. Boaters are trolling with crawler/harness and stick baits as well as drifting jigs tipped with minnows, crawlers, or plastics. - Kevin King, fisheries technician, Peshtigo

Oconto County - Panfish remains the main draw below the dam at Stiles on the Oconto River. Live bait is working well for bluegill and rock bass but also catching some smallmouth. Anglers floating the Oconto River have been catching smallmouth using flies, spinners, and plastics. The mouth of the Oconto River continues to produce catfish, drum, smallmouth and rock bass using a variety of baits and presentations. Walleye and perch anglers out of Pensaukee to Oconto Park II report having limited success. Trolling for walleye in 8 to 20 feet of water has produced some fish using crawler/harness and rip jigging. Along with walleye some very large perch were also being caught. Anglers report perch are being caught are in the 9 to 11 feet of water range adjacent to weed beds and structure. Crawler pieces and minnows are working the best. The bite has been inconsistent. - Kevin King, fisheries technician, Peshtigo

Fishing pressure from Geano Beach Boat Launch has been moderate with most anglers interviewed going after walleye. Walleye anglers have been on a very consistent bite of late with most boats returning to the launch with three to four keepers. Though the bite isn't crazy good, anglers are consistently coming back with a good number of fish, which is much better than earlier this summer. Most anglers were trolling crawler harnesses in waters ranging from 20 feet out to 30 feet of water. Perch anglers are still having a tough time finding good numbers of fish but it is still early for the perch bite on the west shore as the best bite is usually end of August and after. Other fish species caught were freshwater drum, white perch, white bass, and channel catfish. - Derek Apps, fisheries technician, Green Bay

Brown County - Fishing pressure out of Suamico stayed busy this week whether that be from anglers or from pleasure boaters heading out to the bay for some fun in the sun. Walleye anglers found a very consistent bite, with the majority of the boats bringing in three to four keeper walleyes. Most of the walleyes that were caught ranged in size from 16 inches to 22 inches with a good number of larger fish (26-inch-plus) being caught and released to be caught another day. Anglers reported mostly trolling for the walleyes using crawler harnesses with a few anglers getting fish by locating a school and dropping down jigs right on top of them. A few anglers from shore were catching some smaller yellow perch, but it's nice to see kids outside enjoying some family time and fishing. Other fish species caught were: freshwater drum, channel catfish, white bass, and white perch. At Duck Creek, anglers were targeting perch and actually found decent success. This success came in the form of smaller yellow perch but the numbers the anglers were getting sometimes reached into triple digits. Anglers were using various tactics to get the yellow perch to bite including pickle rigs, bait under a float, and just a simple bottom presentation. Walleye has been the main target for anglers launching from the Fox River mouth and running a couple miles north usually. Walleye angler have had a tough time finding decent numbers of walleyes and they are also struggling to keep the non-target fish off their lines, many times white perch or freshwater drum will hit their baits before a walleye has time. Shore anglers from the river mouth have still been doing well catching freshwater drum with the occasional channel catfish mixed in. The river's water temperature is quite high right now with many anglers reporting 82-85 degree surface temperatures. Fish species that have been caught by anglers in the upper portion were freshwater drum, and channel catfish. - Derek Apps, fisheries technician, Green Bay

At Bayshore Park, earlier on in the week weather was unfavorable for fishing but despite that walleye anglers still found semi consistent success. Most boats found themselves catching at least a couple fish for a half days trip. Around half the boats interviewed harvested fish. Boats fishing for perch found similar success to those fishing for walleye. As always the freshwater drum bite has been super consistent and anglers were catching plenty of them. Anglers also caught a few white bass and white perch while out fishing for walleye. The parking lot averaged around six trailers in the morning in the beginning of the week. - Adam Garlie, fisheries technician, Green Bay

Door County - Fishing pressure in Door County this past week was high due to the K/D Salmon Tournament. Although it was a tough bite due to warm water conditions, chinook salmon and rainbow trout were being caught from Sturgeon Bay to Washington Island. Anglers fishing in Baileys Harbor and Sturgeon Bay were catching a mix of chinook salmon and rainbow trout early in the week, but water temperatures rose quickly into the low 70s later in the week and fishing action slowed. The smallmouth bass fishing remains good on Green Bay both from the piers and out on the water. Anglers have been doing well in 4-20 feet of water with reports of an aggressive bite early in the morning. A few anglers reported success with smallmouth bass from Murphy Park Pier, Anderson's Pier, and the brake wall in Egg Harbor. Live bait, in particular leaches, seem to produce the best results. There were a few incidental catches of rock bass and yellow perch in these same locations. Yellow perch fishing has been fairly good with good numbers of fish being caught and fish up to 13 inches have been reported. No individuals targeting walleyes were interviewed this weekend. - Lucas Koenig, fisheries technician, Sturgeon Bay

At Chaudoir's Dock, the majority of the boats out were after walleye with moderate success. About half the boats were trolling using crank baits and the other half were using crawler harnesses. Anglers from boat also caught freshwater drum and white bass. The parking lot had averaged around five trailers in the morning each during the week. Off Little Sturgeon Bay, over the weekend the parking lot was packed to the point where the overflow lot was used. Despite that, most boats on the water were for pleasure and not fishing. Only a few walleye anglers were out and they didn't have much luck landing any fish. Perch anglers had a bit more success and caught plenty of small perch. At Sawyer Harbor, even though there were only a few bass boats out this weekend they still found some fish. They were hooking into 5-15 bass for half a day on the water. While they were out they also caught the sporadic freshwater drum. Perch anglers also found success as well catching 10-25 fish for half a day's trip. Some perch were measured and had lengths around 9 inches. Anglers out fishing for perch caught their fill of goby as well.- Adam Garlie, fisheries technician, Green Bay

Kewaunee County - The slow action over the past week seems to be picking up from Kewaunee north to Sturgeon Bay. The best action has been for rainbows in 200=plus feet of water, with multiple fish being caught and some larger individuals up to 15 pounds. Dodger/fly combos and orange spoons have been working well. King action has been very inconsistent with a few lucky anglers finding a pod of fish while most are lucky to catch one or two. Many anglers report all their bites come just before first light so getting out early is important. Despite a tough king bite the size of the kings has been excellent. Uncooperative weather has made fishing difficult for the KD tournament this past week but anglers still managed to catch over 150 fish of 20-plus-pounds with several 30-plus pounds fish registered. If our weather stays consistent look for action to improve. - Benjamin Thome, fisheries technician, Sturgeon Bay

Manitowoc County - Salmon fishing in Manitowoc and Two Rivers was on a steady rise throughout the week. By the weekend, consistent numbers (from 2-10 fish) were coming in from almost every boat. On top of that, anglers who came in with more fish typically had mixed bags, and every species of salmon and trout was brought in between the two ports over the weekend. Two distinct water depths produced fish consistently: some anglers did well fishing around 120 feet, and some also had success in 200-250 feet. Those fishing deeper (200-250) caught primarily rainbows, but kings and some lakers accompanied them. Green dodger/fly combos 60 plus feet down as well as orange or green spoons on 10-color lead core caught the most fish in the deeper water. The shallower water (120-ish) saw even splits of chinook, coho, and rainbows, with the same presentation and depth fished being effective, but the flies outfished the spoons at this depth. Most of the salmon came on the flies, and rainbows were split between flies and spoons. Some anglers in Manitowoc found some brown trout in 60-70 feet of water, but they reported no difference in lure or water temperature that would isolate that depth for future brown trout catches. Surface temperatures continue to sit in the low 70s, and the temperature begins to drop at the 60-foot below the surface range, where many anglers reported fish. - Jacob Steckmesser, fisheries technician, Mishicot

Peshtigo DNR Service Center area

Marinette County - Blueberries are still being found in some areas. Raspberries are winding down, and blackberries are still waiting their turn. Isolated showers brought more than 2 inches of rain to some areas of the county, while others enjoyed a long awaited 'dry' spell. Many adult monarchs have been seen this week frequenting blazing star and milkweeds. Fishing has been slow but anglers are still picking up smallmouth and perch on the Peshtigo River and a variety of other fish too. The boat landing at the mouth of the Peshtigo River was covered in sand last week. The landing was cleared of the sand buildup on Thursday and a visit to the site on Saturday found new sand buildup had returned. Anglers can still use the launch site, but be aware that the sand may be an issue until it can be cleaned out again. Since August is National Shooting Sports Month, I'll put in a plug for the Peshtigo Harbor Shooting Range. The Range is located southeast of Peshtigo off of Hipke road. The range includes covered shooting benches at 50, 100, and 200 yards. The range is free and open to the public but you must bring your own paper target and clean up after yourself. Dunbar and Athelstane Barrens are very colorful right now with bergamot, asters, sunflowers, blazing star, and numerous other plants in full bloom. These are great properties to explore and find all kinds of wildlife! - Aaron McCullough, wildlife technician, Wausaukee

Sturgeon Bay DNR Service Center area

Potawatomi State Park - All trails are open. Bald eagles, great blue herons, common mergansers and buffleheads have been seen flying over Sawyer Harbor. Many visitors are still spotting wild turkeys mainly by the park entrance. Many flowers are in bloom in the park. A turtle was spotted laying eggs along the rocky shoreline. - Jaclyn Moeri, visitor services associate

Wautoma DNR Service Center area

Waupaca County - Blackberry crop has just started but will not yield heavily until probably next week. Will be a bumper crop. Cannot yet tell if it is going to be a good acorn year. Buck antler growth should be near complete with bucks shedding velvet in about a month. Trout streams starting to get a little low right now and could a spritz of rain to stabilize levels. No inland fishing report, pleasure boat traffic very heavy with the hot weather. The brief dry spell we are in brought about one very good thing - the bugs have really died down. Just a couple deer flies and just a few mosquitos. - Karl Kramer, wildlife technician, Wautoma

Waushara County - It has been a great week here in Waushara County and the weekend looks to be very similar. Water temperatures have been up and even with a slight cooling this weekend the weather looks good. Some fish have been popping even though we are getting into the "dog days" of summer. Fawns have been out and about in full force lately too - I've seen 10 in the last week! Birds are on second and even third nests of the season and fledglings are all over the place. Ducks and geese are starting to fly again and have been seen feeding in fields and flying to different roosts. The blackberries are ripening well and should be ready for picking this weekend, so get out and enjoy the cooler weather and what Waushara County has to offer! - Ben Mott, conservation warden, Wautoma

Oshkosh DNR Service Center area

Outagamie County - Oshkosh DNR fisheries staff and a host of volunteers began the annual bottom trawling survey on Lake Winnebago this week. The trawling assessment provides critical information on year class strength, population trends, and abundance of game and nongame fish species. The walleye catch has been dominated by fish ranging from 15-18 inches as well as yearlings ranging from 8-10 inches, which can be attributed to the strong 2013 and 2016 year classes. Good numbers of crappies and yellow perch ranging from 5-7 inches were also sampled, which should provide future fishing opportunities for anglers. The survey will continue through the first week of August, September, and October. Angler reports continue to indicate productive walleye fishing on Lake Winnebago, particularly on fish ranging 15-18 inches. Anglers are using a combination of methods including trolling in the mud as well as jigging or using slip bobbers on reefs under the right wind conditions. Reports have also indicated good perch fishing action throughout the system; although, many smaller fish are being caught anglers have been coming across some nice sized 9-11 inch fish as well. - Adam Nickel, senior fisheries biologist, Oshkosh

Milwaukee DNR Service Center area

Southern Lake Michigan fisheries team report

Sheboygan County - Fishing pressure was low throughout the week due to windy and stormy weather, however, there was a noticeable increase in anglers and boaters over the weekend as conditions improved. As in previous weeks, boaters still reported most of the success, with anglers reporting little to no success off the piers. There was no reported success off of the piers this week. The water off the North Pier was extremely dirty most of the week, likely resulting from the intense wind and storms that prevented most anglers from even attempting to fish. Anglers were mainly using spoons since the alewives have disappeared, likely to deeper, colder water in the past couple of weeks. The surface temperature of the water remained warm, holding steady at 67 degrees. Success off boats was limited during the week, with the majority of the fish being caught over the weekend. Mainly rainbow trout were caught, along with some coho salmon and chinook salmon, four brown trout, and three lake trout. Most boaters registered their catches with the Cleveland Derby over the weekend. These chinook salmon weighed anywhere from 5.3-21 pounds. Most of the fish were caught in greater water depths of 200-300 feet on spoons, flasher flies, and dipsy divers.

Ozaukee County - Fishing pressure was extremely low during the week due to poor weather conditions. More boaters were present over the weekend to participate in the Lion's Derby. Success off the piers was rare, and although more success was reported from boaters, the catches still remain inconsistent. Only two catches of a small rainbow trout and a carp was caught off the harbor area on Saturday, July 29. They were both caught on spoons. There were hardly any alewives visible throughout the week. The surface temperature of the water was warm and ranged from 65-68 degrees. Success off the boats was hit or miss with some boaters catching a couple of fish and others returning to the ramp with none. Mainly rainbow trout were caught, along with some chinook salmon and coho salmon, and one lake trout. Two rainbow trout that were measured weighed 2.5 pounds and 6 pounds, and two chinook salmon weighed 12 pounds and 18.5 pounds. Catches were reportedly made in water depths ranging from 140-260 feet on spoons and dodger flies.

Racine County - Anglers off the ramp caught between zero and four fish this week. All of the fish caught were caught between 150 feet out to 270 feet of water and anglers ran their lures from 85 feet down up to 20 feet from the surface. Spoons and meat rigs seemed to catch the most fish. Anglers caught coho, king salmon, steelhead, and lake trout. The water temperature was 68 degrees at the surface. At the pier, one brown trout was reported caught this week. The angler caught the fish during the late evening hours on a spoon. The water temperature was 72 degrees.

Kenosha County - From the shore, six brown trout were reported caught this week. All of the brown trout were caught on spoons (green/silver or blue/silver) or tube jigs (pearl, white, or chartreuse). Most of the browns were caught during low light periods, however a couple were also caught during the middle of the day. The water temperature was 70 degrees.

Plymouth DNR Service Center area

Theresa Marsh State Wildlife Area - Local Canada geese are starting to flock up and stage on oats and other small grain fields, cut hay fields, and other open fields and wetlands so now is a good time to start scouting and lining up landowner permissions to hunt the early goose season. DNR staff have seen turkey broods of various sizes, including some newly hatched poults. Prairie flowers are close to peak bloom in grass fields on Theresa, Allenton and Jackson Wildlife Area and other areas. Marsh viewing and picture taking opportunities for Canada geese, puddle ducks, pelicans, great blue herons, egrets, black terns, cormorants, shorebirds, an occasional bald eagle, and other birds are excellent along Highway 28 just west of Highway 41 on Theresa Marsh Wildlife Area. The water level on one of the impoundment south of the highway will remain in a partial drawn down during the next few weeks, resulting in some mudflats being used by shorebirds. Walking on the dikes within the posted Theresa Marsh refuge on both sides of Highway 28 is permitted until Sept. 1 when no-entry refuge restrictions go into place. Fishing for northern pike and bullheads continues to be good above and below the Theresa Marsh dam. We are still looking for a few qualified people to fill the remaining County Deer Advisory Council stakeholder positions in Washington and Ozaukee County. Please visit the "CDAC" website and consider applying to represent your county. The first of two fall CDAC meetings to set 3-year county deer management population goals will be in late August. - Tom Isaac, wildlife biologist, Hartford

Dodgeville DNR Service Center area

Wyalusing State Park -Here at Wyalusing the fishing conditions have been good as the water is high but receding. The bugs are still prevalent so bug spray is needed. We have a hummingbird banding coming up the 10th and 11th this month and visitors are welcome to help. All of our trails are open and cleaned up after the storm damage we had in both Nelson Dewey and Wyalusing State Park. - Becky Mumm, naturalist

Horicon DNR Service Center area

Horicon Marsh State Wildlife Area - Archery, birding, cooking, hunting and fishing are among the fun things to be taught by Department of Natural Resources staff and expert volunteers during the free and family-friendly August Horicon Marsh Outdoor Skills Day on August 5 from 9:30 a.m. to 12:30 p.m. The Horicon Bowmen and the DNR are proud to offer the archery camp at this year's event. People of all ages can try archery using the National Archery in the Schools Program (NASP) equipment. Watch a cast iron cook in action and taste delicious treats, all prepared over the campfire. Members of the Wisconsin Trappers Association will have a booth with pelts, traps and information for anyone who is interested in learning more about regulated trapping. Certified Hunter Safety Instructors will be available with firearm action sets to demonstrate proper firearm use and safety along with laser guns for safe target practice. Climb into a harness and learn about tree stand safety. Check out a turkey blind and try your hand at some special calls. Expert birders will be on hand to show the basics of binocular use. Try your hand at tying your own bluegill fly as well! Native prairies are in their full glory with many species in bloom. Compass and cup plant, yellow and purple coneflower, swamp milkweed, blue vervain, and goldenrod put on a beautiful show of color. Pollinators and butterflies are visiting these forbs in huge numbers so bring out the macro lens and make some great photos! Shorebird locations are drying up but the north end of Horicon Marsh on Hwy. 49 and Old Marsh Road seem to have the most potential at this time. The Horicon Marsh Education and Visitor Center is located between Horicon and Mayville on Highway 28. For a detailed list of all Horicon Marsh Education and Visitor Center special events, please visit the Friends of Horicon Marsh website at www.horiconmarsh.org [EXIT DNR].

La Crosse DNR Service Center area

Vernon County - DNR Wildlife Management personnel translocated several timber rattlesnakes from residential settings along the Vernon County Mississippi River bluffs during the past 2 weeks. The translocations were conducted in order to prevent undesirable encounters. In these instances, the homeowners recognized the potential harm the rattlesnakes could cause if a person or pet was bitten, but they also did not want the snakes harmed. Fortunately, timber rattlesnakes, a species of Special Concern and a Protected Wild Animal, are rather docile unless provoked. Adult males and non-gravid adult females prefer deciduous forests and woodland edges in agricultural settings during the summer. Gravid (pregnant) females and juveniles prefer to remain in open-canopy bluff prairies during the summer because of higher preferred temperatures, but they avoid overheating by taking advantage of various structures to provide shade, such as brush, trees or rock shelves. Timber rattlesnakes emerge from hibernation as early as mid-April but may continue to emerge well into June. They remain active until as late as mid-October, with the females that give birth in a given year remaining active longer than other individuals. Timber rattlers breed primarily in August and females give birth the following mid-August to mid-September. Individual females in WI usually produce young only once every 3-4 years. People who experience timber rattlesnake occurrences are encouraged to contact their local DNR office for assistance or the DNR Customer Service Information Line at 1-888-936-7463 between the hours of 7 a.m. and 10 p.m. seven days a week. - Dave Matheys, wildlife biologist, Viroqua
