Stocking Notes
1 - indicates fish purchased and stocked by private citizens and sporting groups.
2 - indicates fish purchased by the DNR for stocking.

Stocking Fish Sizes
Fry - Newly hatched fish that are ready to be stocked usually called "swim-ups". Walleye fry are 1/3 of an inch or around 8 mm.
Fingerling - 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.

Status of the Fishery (as of 08/09/2010)

Lake Waconia is a 2,996 acre lake with a maximum depth of 37 feet, located in north central Carver County. Lake Waconia provides bountiful recreational opportunities. Fishing and boating are very popular. Beaches provide swimming opportunities and wind surfers frequent the lake on gusty days. Water quality in Lake Waconia is fair, compared to other West Metro lakes. By late summer most species of fish cannot inhabit water much deeper than 18 feet for extended periods of time. Anglers should keep this in mind when pursuing walleye and crappie. Fishing in water deeper than 20 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 Lake Waconia is diverse and healthy. Walleye average length was 19.1 inches. Average weight was 2.56 pounds. Abundance was average, weight was above average for this type of lake. Walleye are stocked into Lake Waconia every year. Fry are stocked in three out of four years and fingerlings in the other year. Fingerlings will be stocked in 2011. Northern pike numbers were high compared to historic averages for Lake Waconia. In the 2010 population assessment largemouth bass abundance increased compared to past surveys, but is below average for lakes similar to Waconia. Standard lake survey gear does not consistently provide an accurate estimate of largemouth bass abundance. Muskellunge are present in Lake Waconia. Both abundance and mean weight were the highest ever observed. Stocking of muskellunge occurs once every two years.

Five species of panfish are present in Lake Waconia. Black crappie abundance is above average compared to similar lakes, but low compared to historic catches within Lake Waconia. Few large fish were sampled. Average length was just over 7 inches. Bluegill abundance increased to a level not seen in Lake Waconia since 2002. Abundance remains above average compared to similar lakes and average weight increased slightly. Over 30% of sampled bluegill were greater than 6 inches. Yellow perch abundance in Lake Waconia is above the average. Mean weight of yellow perch was below average. Average length was 6.6 inches. Pumpkinseed were sampled at below average abundance as well. White crappie were also sampled.

Rough fish are present in low numbers. Common carp abundance increased slightly since the 2008 survey, but remains low compared to historic catches from Lake Waconia. Black bullhead were not sampled in 2010. Only one yellow bullhead was sampled. Both abundances are at all time lows. Freshwater drum were also sampled.

Culling of Double-crested Cormorants (DCCO) is conducted by the US Dept Agriculture in an effort to control the resident population on Coney Island. This native species, which population has recovered after the ban on DDT, has been the focus of public input and debate. To date, no evidence exists to suggest the DCCO colony has had any adverse effect on fish populations in Lake Waconia.
