Lake DuBay, T26N, R7E, Section 33 Surface Acres = 6,653, Maximum Depth = 30 feet, Secchi Disk = Not available A soft water drainage lake (impoundment) having slightly acid, medium brown water of low transparency. The immediate shoreline is predominantly upland (95 percent) with the remainder being wetland. Sand is the dominant littoral material, with lesser amounts of rubble, gravel and muck. Fish inhabiting the flowage include walleye, northern pike, yellow perch, black crappie, pumpkinseed, black bullhead, brown bullhead, white sucker and carp. Migratory waterfowl make considerable use of this flowage. Emergent and submergent vegetation are common in the littoral area. Public access is possible from one county and two state access points. Of the flowage's 42.3 miles of shoreline, 0.9 mile is public. Developments on the shoreline include 122 dwellings, a wayside park, Ashley County Park and DuBay County Park. The water control structure, owned by the Consolidated Water Power Company, is used to generate electric power. The dam has a head of 25 feet. Streams entering the flowage include the Wisconsin River, the Big Eau Pleine River, the Little Eau Pleine River, the Little Eau Claire River, Peplin Creek, Johnson Creek, Hog Creek and five unnamed streams. Although Lake DuBay extends into Portage County, the acreage and shoreline figures for Marathon County represent the entire flowage. In 1977 the flowage experienced a winterkill, the first of any significance known to have occurred. This circumstance was likely precipitated by a significantly reduced stream flow in the Wisconsin River due to drought conditions.

Average Water Quality in Late Summer during the past 5 Years for Dubay Lake in Wisconsin (Central) basin.

Note: No numbers by the first = in water clarity, etc. means no samples on this lake in the past 5 years in late summer.
Water Clarity in feet = 2.1 for 10 samples in 2006 compared to 9 feet for 229 samples in the basin.
Chlorophyll A in ug/l = for 0 samples compared to 14 ug/l for 62 samples in the basin.
Total Phosphorus in mg/l = for 0 samples compared to 0.06 mg/l for 72 samples in the basin.
Public Perception of water conditions = 2 to 5 for 10 samples in 2006 compared to 2 for 204 samples in the basin.
Where the scale is 1-5 1= Beautiful, could not be any nicer; 2= Very minor aesthetic problems - excellent for swimming, boating, enjoyment; 3= Swimming and aesthetic enjoyment slightly impaired because of algae levels; 4= Desire to swim and level of enjoyment of the lake substantially reduced because of algae (would not swim, but boating ok); 5= Swimming and aesthetic enjoyment of the lake nearly impossible because of algae level.
Trophic state is another indicator of water quality.
