What aquatic invasive species are found in Long Lake?
Join us in the fight to prevent the spread of invasive species These sneaky creatures can hitch a ride on boats, clinging onto propellers, anchor lines, and trailers. They can even survive in hidden places like bilge water and ballast tanks, or disguise themselves in dirt and sand that sticks to nets, buckets, anchors, and waders. But don't worry, we have the power to stop them in their tracks with just a few simple steps. So let's do our part and protect our waters from these unwanted invaders.
History & Status of the Fishery
Long is a productive, 285-acre lake located in the City of Long Lake in Hennepin County. There is a city-owned public boat access and beach on the west shore of the lake. Maximum depth is 33 ft and water clarity in early July was 2.2 ft. At that time in early July, a temperature-oxygen profile indicated the lake was strongly stratified with poor (<2 ppm) dissolved oxygen below 10 feet. A population assessment consisting of summer gill nets and fall trap nets was conducted in 2013 to characterize the game fish community.
Walleye stocking in Long Lake began in 1989 when fry were introduced. Fry stocking maintained a modest Walleye fishery from then through the 1990's. In 2001, a switch was made to larger fall-stocked fingerling Walleye. Varying fingerlings rates and one fry stocking took place in 2003, 2005, and 2007, when the lake was part of a MN DNR Fisheries Research study. The current management plan (effective 2009) calls for 262 lbs of Walleye fingerlings to be stocked in odd-numbered years.
Summer gill nets sampled 20 Walleye-3.3/net. Relative abundance was nearly average (2.8/net) compared to similar lakes statewide. Walleye size structure was balanced, consisting of two distinct size groups of sub-20-inch fish, either 11-13 inches (55 percent of total) or 18-20 inches (45 percent of total). These groups corresponded to the stocked 2011 (age 2) and 2009 (age 4) year classes, with one fish from the 2007 year class (age 6). Walleye averaged 14.6 inches and 1.2 lbs.
Forty Walleye were sampled in fall trap nets- 4.4/net. Sampled-fish sizes were 13.2-21.6 inches and averaged 15.5 inches and 1.3 lbs. Size structure didn't appear as balanced as the gill nets, likely because 70 percent of the fish were between 13 and 15 inches. Five fish over 20 inches were sampled as well. These larger fish were not observed in the gill nets. Growth of Walleye was slightly slower than the average compared to other similar lakes in the West Metro Management Area. Walleye averaged 15.1 inches by age 4.
Long Lake is eutrophic, and, at times, portions of the water column may suffer from lack of oxygen. High summer water temperature and subsequent low dissolved oxygen may push the limits for optimal growth and survival of Walleye.
Northern Pike were moderately abundant. At 4.0/gill net, catch was near average (3.8/net) when compared to other similar lakes. Pike abundance was higher than that of the previous assessment (1.7/net in 2008), but lower than the mean (5.7/net) over the past 4 assessments dating back to 2001. The size structure was skewed toward larger individuals. Sixty-three percent of the Northern Pike were relatively evenly distributed between 26.0 and 31.0 inches. They ranged from 21.0 - 35.4 inches, averaging 27.6 inches and 4.9 lbs. The weight of an average pike was heavier than the 75th percentile value (3.5 lbs) when compared to other similar lakes. Ages ranged from 3 to 7. Pike grew faster than other lakes in the West Metro Area, reaching 27.6 inches by age 5.
Abundance of Bluegill in fall trap nets was moderately high (45.4/net), with size structure skewed toward larger fish. Forty-two percent were between 7.0 and 7.5 inches. Bluegill ranged from 3.1 - 8.0 inches, averaging 6.2 inches and 0.2 lbs. Bluegill mean weight was moderately high when compared to other similar lakes. Catch rates have varied over the previous 4 assessments; however, mean weight has remained relatively high (mean = 0.25 lb). Age of Bluegill in the sample ranged from 1 to 5. Growth was fast compared to other similar lakes. Bluegill were 7.0 inches by age 3.
Black Crappie were abundant (16.7/gill net) but size structure was small. Gillnet catch was the highest observed in the previous 4 assessments dating to 2001. Catch during these assessments averaged 6.7/net. In the 2013 assessment, lengths ranged from 4.1 - 8.5 inches, with 45 percent between 7.5 and 8.5 inches. Crappie averaged 6.5 inches and 0.2 lbs. Growth was fast compared to other similar, as fish averaged 8.1 inches by age 3. Fall trap nets collected fewer Black Crappie, but the size structure was larger. Forty-six crappie were sampled in the trap nets (5.1/net); of these, 85 percent were between 8.5 and 9.5 inches. These fall-sampled fish ranged from 5.6 to 9.5 inches and averaged 8.4 inches.
Yellow Perch abundance (13.2/gill net) was typical of lakes of this type. From 2001-2008, (past 4 assessments), relative abundance has ranged from 1.8-24.8/net, averaging 10.0/net. In 2013, all perch sampled were between 5.8 and 7.7 inches. The average fish was 6.6 inches and 0.1 lbs. All Yellow Perch were from the 2010 year class (age 3). Growth was fast compared to other similar lakes.
Other species sampled during the assessment were Black Bullhead, Common Carp, Golden Shiner, Largemouth Bass, Green Sunfish, hybrid sunfish, Pumpkinseed, White Sucker, and Yellow Bullhead. Passive sampling gear, such as trap and gill nets, are not effective methods for collecting Largemouth Bass, so the numbers from the 2013 assessment are not necessarily representative of the entire population. Electrofishing is the typical method for Largemouth Bass assessments but was not conducted.
A fish kill on this lake, reported by several people, occurred on or near August 14, 2011. Given the description, timing, lake conditions, and a similar occurrence at another local lake, the small-scale die-off of mostly Black Crappie and Bluegill appeared to stem from thermal stress-a combination of low oxygen and increased bacterial levels when fishes' physiological demands run high. No broad, long-lasting depletion of the overall fish community was apparent from this assessment's results, though it could reflect conditions where coolwater fish species might not thrive.
