Overview

Location

Jefferson County. T6N-R14E, Sections 19, 20, 29 and 30. 480 acres.

Description

Description

Rose Lake is a shallow, hard water seepage lake surrounded by wetlands, oak openings, and steep hills that provide fantastic views of the lake. With a maximum depth of 5 feet, Rose Lake contains a submerged aquatic plant community dominated by Illinois pondweed, grass-leaved pondweed, and coon's-tail. Other aquatics include common water-milfoil, common pondweed, comb pondweed, and common bladderwort. Common and star duckweed with common water-meal float on the surface. The west side of the lake is dominated by a large floating mat of American woolly-fruit sedge, blue-joint grass, and spike-rush. The exposed mud flats attract numerous shorebirds such as pectoral sandpiper, least sandpiper, solitary sandpiper, and lesser yellowlegs. The lake and surrounding wetlands are also important breeding habitat for black tern (Chlidonias niger), black-crowned night-heron (Nycticorax nycticorax), and redhead (Aythya americana). Other breeding birds are Sandhill crane, great blue heron, pied-billed grebe, American coot, common moorhen, blue-winged teal, ruddy duck, tree swallow, bank swallow, and marsh wren. Large numbers of yellow-headed blackbirds also nest here. American white pelicans began using the wetland in 2003 when over 800 were recorded. Soft-stem bulrush and cat-tails ring the north, south and east shores. Numerous freshwater sponges and a diverse dragonfly/damselfly population indicate a lack of serious water quality problems. The wetlands are also rich in wildlife with many species of mammals, reptiles, and amphibians. Prairie, savanna, and wetland habitats are being restored around the lake. Rose Lake is owned by Jefferson County and was designated a State Natural Area in 2006.

Maps

The DNR's state natural areas program is comprised of lands owned by the state, private conservation organizations, municipalities, other governmental agencies, educational institutions and private individuals. While the majority of SNAs are open to the public, access may vary according to individual ownership policies. Public use restrictions may apply due to public safety, or to protect endangered or threatened species or unique natural features. Lands may be temporarily closed due to specific management activities. Users are encouraged to contact the landowner for more specific details.

The data shown on these maps have been obtained from various sources, and are of varying age, reliability, and resolution. The data may contain errors or omissions and should not be interpreted as a legal representation of legal ownership boundaries.

Recreation

Very few State Natural Areas have public facilities, but nearly all are open for a variety of recreational activities as indicated below. Generally, there are no picnic areas, restrooms, or other developments. Parking lots or designated parking areas are noted on individual SNA pages and maps. Trails, if present, are typically undesignated footpaths. If a developed trail is present, it will normally be noted on the SNA map and/or under the "Access" tab. A compass and topographic map or a GPS unit are useful tools for exploring larger, isolated SNAs.

Non-DNR lands
