Beaver Lake is a 65-acre, class 40 FiN lake that borders the cities of St. Paul and Maplewood. Managed by Ramsey County, Beaver Lake County Park provides grills, playground, walking path, picnic shelter and tables, ample shorefishing, and a fishing pier. The sport fish community consists of Black Crappie, Bluegill Sunfish, Channel Catfish, Hybrid Sunfish, Northern Pike, Pumpkinseed Sunfish, and Yellow Perch. Fingerling and yearling Channel Catfish have been stocked every year from 1997 to 2009 (total number = 28,026 catfish) from 2012 -2014 another 6400 yearlings and in 2014 100 adults were stocked. Beaver Lake recently experience back to back winter kill events (2013 and 2014) with a severe event occurring in the winter 2013. The large predator community is still trying to recover from these 2 events.
Northern Pike and Channel Catfish provide anglers at Beaver Lake an opportunity to catch larger gamefish. Northern Pike gill net catches stayed consistent the last 3 fish surveys (2000, 2005, and 2010) ranging from 5 to 6 pike/gill net but declined in 2015 to 1.5/gill net. Gill netted pike averaged 21.6 inches and 2.24 lb. Beaver Lake has a history of providing a quality Largemouth Bass fishery however none were observed in any of the sampling gears during this survey. It is anticipated that Largemouth Bass adults will be stocked in 2016 to reestablish the Largemouth Bass community in Beaver Lake. Channel Catfish have been a primary management species since 1997. Two (2014 yearling stocking) channel catfish averaging 14.48 inches were sampled using gill nets. Anecdotal angler information has revealed anglers were catching adult Channel Catfish prior to the winter of 2013, however many large dead catfish were observed after the recent winter kill events (2013-2014) and it appears that the large catfish are gone from the system at this time.
Panfish numbers varied during 2015 fish survey. Bluegill numbers (9.63/trap net) were down from 2010 survey (30.2/trap net). Of the Bluegills (n=80) sampled using trap and gill nets, none were above 6.0 inches. Black Crappie numbers are modest (4.5/gill net, 2.25/trap net). Approximately 75% of the crappies sampled were 7.0 inches or longer, with one fish exceeding 10.0 inches. Yellow Perch numbers (25.5/gill net) are high and are an improvement from the 2005 gill net catch of 1.5/gill net. Yellow Perch relative abundance ranged from 1 to 186 perch/gillnet in the 5 fish surveys prior to 2010 (1980, 1990, 1995, 2000, 2005, 2010). The reestablishment of a decent Yellow Perch forage base should bode well for the predator populations of Beaver Lake. Other fish seen during this survey in low abundance were 3 Green Sunfish, 8 Pumpkinseed Sunfish, 1 Golden Shiner and 9 Black Bullheads.

Recreational activities such as recreational boating, angling, waterfowl hunting, and diving may spread aquatic invasive species. Some aquatic invasive species can attach to boats, while others can become tangled on propellers, anchor lines, or boat trailers. Many species can survive in bilge water, ballast tanks, and motors or may hide in dirt or sand that clings to nets, buckets, anchors, and waders. Fortunately, completing simple steps can prevent the transport of aquatic invasive species.
