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.

Status of the Fishery (as of 05/31/2011)

East Graham, in Nobles County, is one of several lakes that are connected to the West Fork of the Des Moines River. It is a 604-acre lake with a maximum depth of 8 feet. East Graham has a history of low dissolved oxygen in winters as it was opened to liberalized fishing 16 times from 1952 to 1982. A Helixor aeration system was installed in 1985 and winterkill has not occurred since then. In 2007, Murray County replaced the Helixor system with Power House Ice Eaters. East Graham is managed primarily for walleye and northern pike and secondarily for black crappie. A population assessment was conducted during the week of May 31, 2011 using 3 gill nets and 10 trap nets.

The catch rate of walleye in gill nets was 7.3 per set, which was within the expected range for lakes similar to East Graham. Many (63%) of the fish were 14 inches and greater with an impressive average length of 16.5 inches. Ageing information from bone structures indicated (90%) of the fish aged came from the 2008 and 2009 fry stocking. Previous surveys on East Graham also documented success of fry stocking. The odds certainly fall in your favor when you hook up with a walleye on East Graham it will be a "keeper".

Northern pike catch rates in East Graham have been relatively consistent over the years. The catch rate in gill nets was 2.0 per set in 2011, 3.7 per set in 2007, 4.0 per set in 2003, 4.0 per set in 1999, and 2.6 per set in 1995. The large watershed and a connection to the West Fork of the Des Moines River likely contribute to the consistent northern pike abundance. No northern pike have been stocked in East Graham since 1994. Total lengths ranged from 14.1 to 32.8 inches with a mean of 23.8 inches. There is real potential to catch some northern pike in the middle of summer if an angler would target the cool water refuge of field tile inputs.

The black crappie trap net catch rate in East Graham was 2.6 per set and within the expected range of lakes similar to East Graham. Total lengths ranged from 6.6 to 12.2 inches with an overall average of 9.9 inches. The overall relative weight for all length groups was 110, which indicates the fish are pleasantly plump. The crappies currently in East Graham are not trophies but can provide some action when other species are not cooperating.

The yellow perch gill net catch rate in East Graham was up from 1.3 fish per set in 2007 to 6.0 fish per set in 2011. Despite the unimpressive catch rate for a Windom area lake, the yellow perch catch rate was the highest ever recorded at East Graham. Lengths of yellow perch in East Graham ranged from 5.6 to 9.3 inches. Yellow perch in East Graham are not trophies, but in a few years could provide some decent fishing.

The black bullhead catch rate in gill nets was 62.7 per set, which was within the expected range of lakes similar to East Graham. Total lengths ranged from 5.8 to 11.5 inches with a mean of 8.3 inches. The black bullhead population is down from 2007, but the overall size has increased from an average size of 6.5 inches in 2007 to 8.3 inches in 2011.

Other species captured in 2011 were bigmouth buffalo, channel catfish, yellow bullhead, common carp, bluegill, green sunfish, orangespotted sunfish, white suckers, johnny darter, emerald shiner, and fathead minnow.

Efforts to improve the health of the lake should focus on best management practices within the watershed. Improvements and education in land stewardship will often have secondary benefits to the lake in the way of quality and quantity of habitat. Generally, improvements in the quality and quantity of lake habitat will mean direct improvements of the fishery.
