History & Status of the Fishery
North Union, Stony, and Lottie (Taylor) lakes form a chain of lakes between Brophy and Cowdry Lakes in Douglas County. North Union Lake is the upper or first lake in this chain of interconnected lakes. Brophy Lake discharges into North Union. North Union outlets to Stony Lake. None of these three small basins have public landings, but anglers can utilize access sites on Cowdry and Brophy Lakes and navigate small watercraft throughout the chain via flowage channels. Access to these lakes with larger, high profile boats is constrained by bridge crossings and road culverts.
The lakes in this chain are small and relatively unique in that shoreline development has been limited and much of the natural shoreline remains intact. Water quality and clarity are very good. Water transparency at time of the August survey was measured at 19.0 feet. Near-shore areas support lush vegetative growth including bulrushes and water lilies. These habitat characteristics are ideal for Northern Pike, Largemouth Bass, and Bluegill.
Bluegills are abundant in North Union and accounted for most of the total gamefish catch. Average size of Bluegills caught in trap nets was 6.8 inches. The largest Bluegill captured measured 8.4 inches. Ten percent of the total catch of Bluegills were 8.0 inches and larger. Black Crappie catches were low, but crappies are typically difficult to catch in mid-summer surveys. Crappies are anticipated to be more abundant than reflected in survey catch statistics. The largest Black Crappie caught in the survey was 10.1 inches long. Northern Pike are abundant in North Union Lake, though most of the fish caught in the survey were small. Average length of pike captures was 19.6 inches long. Navigation restrictions prevented access with an electrofishing boat to survey the Largemouth Bass population. Only a few Largemouth Bass were caught in the survey nets. Habitat conditions are excellent for Largemouth Bass and this popular gamefish is projected to be abundant.
Anglers and other outdoor recreationists looking for a quiet lake should check out the North Union, Stony, and Lottie lake chain. This chain of lakes provides a remote lake setting in close proximity to the city of Alexandria. Lake Brophy County Park is currently in development and will encompass the West side of North Union Lake. Contact the Douglas County Park Division for more info on this county park.
North Union Lake was designated as an infested water in 2011 after discovery of zebra mussels in upstream lakes. Recreational users should take necessary precautions to prevent further spread of invasive species. Drain all water and remove all aquatic vegetation from your boat and trailer when leaving any body of water. Updated information on invasive species infestations can be found on the MN DNR website.
