Bennett Lake is a popular local fishing resource in Central Park, City of Roseville. The lake is 23 acres in size and has a maximum depth of nine feet. An aeration system located on the east shore prevents winterkill and a fishing pier is located on the west shore. Additionally, there are many points around the lake at which shore anglers can access the lake. The lake is managed for bluegill, channel catfish, black crappie and northern pike. Fish management consists primarily of stocking panfish and catfish in the spring. Central Park provides many amenities including ballfields, playgrounds, bathrooms, picnic areas, walking paths and a band shell.
Bluegill are very abundant and can be readily caught from the fishing pier. The average length of fish sampled in 2011 (4.8 inches) was smaller than the previous survey (5.6 inches) though abundance was similar. However, the lake is stocked almost annually in the fall with large bluegill measuring up to 8.5 inches. A few small black crappie were sampled in 2011, the average length was 5.5 inches. Historically the black crappie catch and size structure has varied greatly from survey to survey and this may represent only a temporary drop in abundance. Northern pike were the most abundant predator species seen in this survey with twelve of them caught that ranged from 18.9 inches up to 31.3 inches in length. Northern pike are not stocked into Bennett and are sustained through natural reproduction. Walleye have been stocked into Bennett most recently in 2010 and the three fish sampled were all from this stocking (age one fish, under 10 inches long). Channel catfish, which have been stocked almost every year since 1996 were found in low numbers, with just one fish caught that measured 11.1 inches. Past surveys have caught channel catfish up to 19 inches long. No largemouth bass were seen during the 2011 survey. Other species sampled included black bullhead (six fish), golden shiner, yellow perch, green sunfish, pumpkinseed sunfish and hybrid sunfish.
