Private stocking includes fish purchased by the DNR for stocking and fish purchased and stocked by private citizens and sporting groups. Stocking Fish Sizes Fry - Newly hatched fish that are ready to be stocked usually called "swim-ups". Walleye fry are /3 of an inch or around 8 mm. Fineeding - Fingerlings are one to six months old and can range from a size of one to twelve inches depending on the species. Walleye fingerlings range from three to eight inches each fall. Yearling - Yearling fish are at least one year old. A one-year-old fish can range from three to twenty inches depending on the species. Walleye yearlings average from six to twelve inches. Adult - Adult fish are fish that have reached maturity. Depending on the species, maturity can be reached at two years of age. Walleye reach maturity between the ages of four and six years. Fish Consumption Guidelines These fish consumption guidelines help people make choices about which fish to eat and how often. Following the guidelin es enables people to reduce their exposure to contaminants while still enjoying the many benefits from fish.

Contaminants listed were measured at levels high enough to warrant a recommendation to limit consumption. Listing of consumption guidelines do not imply the fish are legal to keep, MN DNR fishing regulations should be consulted. Dioxin Mercury PCBS - Polvchlorinated biphenvls PFOS - Perfluorooctane sulfanate Status of the Fishery (as of 06702/200) Spring Lake is a 59 acre lake with a maximum depth of 37 feet, located in north central Scott County. Spring Lake provides ample recreational opportunities. Fishing and boating are very popular. Water quality in Spring Lake is poor, compared to other West Metro lakes. By late summer most species of fish cannot inhabit water deeper than 2 feet for extended periods of time. Anglers should keep this in mind when pursuing walleye and crappie. Fishing in water deeper than 2 feet in mid to late summer could yield very few fish. Boaters should also keep in mind, new laws require the drain plug be removed while on public roadways. The predator community in Spring Lake is expanding. Walleye average length was 6.7 inches. Average weight was 2.0 pounds, above average compared to similar lakes. Abundance was above average and showed an increase compared to the previous survey. Walleye fingerlings are stocked in odd numbered years. Nearly 70% of sampled fish were young fish, either age one or three. Northern pike numbers were on par with historic averages for Spring Lake. In the 200 population assessment largemouth bass abundance increased compared to past surveys, and is average for lakes similar to Spring Lake. Standard lake survey gear does not consistently provide an accurate estimate of largemouth bass state, mn. us/lakefind/showreport. html?do wnum= /3/202

5 Lake information report: Minnesota DNR Page 5 of 5 abundance. One 4.8 inch adult white bass was sampled. White bass were not seen in Spring Lake before Since then, they have been sampled in three different surveys. Five species of panfish are present in Spring Lake. Black crappie abundance is high. Few large fish were sampled, but the average size has improved since the 2008 survey. Average length was 7.8 inches. Bluegill abundance decreased slightly and is below the average range for this type of lake. Spring Lake bluegill average size is very good, over 6.5 inches. Over 70% of sampled bluegill were greater than 6 inches. Nearly two-thirds were 7 inches or larger. Yellow perch abundance increased to a level within the average range. Mean weight of yellow perch was average. Average length was 6.8 inches. Pumpkinseed were sampled at a low abundance. Hybrid sunfish were also sampled. Rough fish are present in below average numbers. Common carp abundance increased slightly since the 2008 survey, but remains below average. Black and yellow bullhead were sampled at below average abundance. White sucker abundance was high and average weight was above average. On May 26th, 200 a resident reported dead fish on the south shore of Spring Lake. Given the time of year, water temperature conditions at the time and recent past springtime fish kills, a bacterial-caused die-off is the prime suspect. In 2005 columnaris was confirmed as the cause of a similar fish kill. For fertile lakes that warm rapidly, this phenomenon is common. Based on biennial fish population assessments, these die offs have not caused noticeable declines in Spring Lake fish populations.
