Fish Stocking Activity

Fish Stocked by Species for the Last Ten Years

Year Species Size Number Pounds
2012 Rainbow Trout yearlings 506 675.6
2009 Rainbow Trout yearlings 1,000 388.4
2008 Rainbow Trout yearlings 1,587 865.5
2007 Rainbow Trout yearlings 1,298 706.4

2005 Rainbow Trout yearlings 1,204 675.2
2004 Rainbow Trout yearlings 1,500 807.5

Privately Stocked Fish
* indicates privately stocked fish. 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 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 06/25/2012)

Little Long Lake is a deep, cool, clear lake located in Hennepin County. This type of lake (Lake Class 32) is rare within the metropolitan area of Minneapolis, and therefore offers unique fishing opportunities, among them "two-story" management that includes trout. Rainbow trout management via stocking yearlings, absent from 2009-2012, has resumed to provide a put-and-take winter fishery. A public boat launch is located on the northeast shore of the lake. Motors with more than 10 horsepower may not be used.

In 2012, Three Rivers Park District Board of Commissioners approved a purchase agreement for 127 acres of undeveloped land adjacent to the lake. The land was once the site of Camp Kingswood, owned by the Minnesota United Methodist Church. Three Rivers Park District will maintain the land for public use, focusing on basic stewardship and resource management.

During the summer population assessment, no rainbow trout were sampled. This is not surprising, since no stocking occurred after spring 2009. Stocking resumed after this assessment, in time to provide fish for the 2013 winter trout season. Typically, in Little Long Lake, as with the Metro's other trout lakes, anglers catch nearly all the stocked trout soon after season openings. A few survivors might remain for later open-water trout seasons, which open in mid-May.

Northern pike were caught at a below-average value, and the fish were of average size. Sampled northerns ranged from 16.4 to 27.4 inches in length, with 20.9 inches as the average. The average northern weighed a little over 2 pounds.

Bluegill and pumpkinseed sunfish were caught at below average rates, and the fish were of average size. Mean weight for bluegill and pumpkinseed was 0.15 lbs and 0.21 lbs, respectively. About 58% of sampled bluegill and 42% of sampled pumpkinseeds were greater than 6 inches.

Black crappie, hybrids of the sunfish species, largemouth bass, bowfin (dogfish), and yellow bullhead were all present in low numbers. The bullhead were found to be well above average in weight.
