Jointly managed by the MNDNR and the City of Eagan, Lemay Lake is a 37-acre, class 37 FiN Lake located at Pilot Knob and Jurdy Road. Moonshine Park provides shorefishing opportunities and a place to launch a canoe or kayak. The sport fish community consists of Black Crappie, Bluegill, Green Sunfish, Hybrid Sunfish, Largemouth Bass, and Pumpkinseed Sunfish. Lemay Lake has an aeration system maintained by the City of Eagan to prevent winterkill and protect the gamefish community. Bluegill and Largemouth Bass have been stocked periodically between 2002 and 2005 and again in 2014 to create a fishable centrarchid community. Water clarity has fluctuated from 1.5 feet in 2004, 4.0 feet in 2009 and back down to 3.5 feet in 2014.

The winter of 2013/2014 induced winter kill conditions in LeMay Lake in spite of winter aeration efforts. The 2014 population assessment consisted of trapnetting and electrofishing only. Gillnets were not used in this survey. The 2014 results reveal how winter kill can affect a small lake.
Electrofishing revealed LeMay's Largemouth Bass population has declined substantially since the 2009 survey. No Largemouth Bass were sampled in 2014 by electrofishing and only one 5-inch fish was seen in the trapnets.
At this time, panfish abundance is not good due to winter kill. Of the eight Bluegills sampled using trap nets, all were adult fish stocked earlier this spring by MN DNR. Black Crappie abundance was low, with only eleven Black Crappie observed and only one exceeding 7.0 inches in length. Varying numbers of Green Sunfish (n=2) and Hybrid Sunfish (n=18) were sampled in assessment. Black Bullhead numbers are down considerably from the 2004 initial survey. The Black Bullhead population is roughly unchanged from 2009 when 2.40 Black Bullhead were sampled per trapnet. A total of twenty six Black Bullhead were observed in this survey. Other fish sampled were 3 medium sized Golden Shiners.
