Fish Stocked by Species for the Last Ten Years
|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.|
Timber Lake, near Wilder, is a typical pothole prairie lake located about 5 miles south of Windom. Timber Lake has a maximum depth of around 8 feet and has a history of winterkill. A relatively consistent yellow perch/northern pike fishery seems to be maintained in spite of the partial winterkill history. Timber Lake is managed primarily for northern pike and secondarily for yellow perch and black crappie. A resurvey was conducted during the week of July 6, 2005 using 3 gill nets, 9 trap nets, and 3 seine hauls.
The catch rate for northern pike was within the expected range (2.0/gill net) for the Windom Area. During the 2004 survey, total lengths ranged from 17 to 26 inches and averaged 19 inches. Only 2 year class of fish were sampled (2000 and 2002) which indicated the population may have limited habitat for natural reproduction. Northern pike catch rates have varied historically from 1.0/gill net in 1998 to 11.7/gill net in 1994. Most of the variation in catch rates among years for northern pike can be attributed to varying water levels at the time northern pike spawn. During years in which high water persists during the spawning and hatch period, northern pike are able to utilize the flooded vegetation and successfully reproduce. The high catch rate in 1994 was likely a result of the high water from 1993. Although numbers of northerns have been higher in other years, anglers do have the opportunity to catch some nice "toothies" on Timber Lake.
The catch rate for yellow perch was nearly 3 times the normal range for Windom Area lakes. Total lengths ranged from 4 to 12 inches and averaged 8.5 inches. Great sizes of fish can be caught but may take some persistence to produce a stringer full of fillets. Six year class of yellow perch were sampled during the survey which indicated consistent natural reproduction. Natural reproduction appeared to be excellent as many Age 0 fish were sampled. Growth rates are quite good as an Age 4 perch was nearly 11 inches. The take home message is that if an angler is targeting yellow perch, Timber Lake is worth trying for an afternoon as good numbers and sizes are abundant.
No black crappie were sampled during the 2004 survey which may indicate the population is in a building period. It is likely that the abundant perch population is dominating the panfish population.
The black bullhead catch rate was within the expected range but most are small sized. The bigmouth buffalo catch rate was the highest ever recorded on Timber Lake while the common carp catch rate was the second highest ever recorded. The abundant bigmouth buffalo and common carp probably contribute to the limited submergent vegetation.
A total of twelve species of fish were sampled during the 2004 survey. Other species sampled were fathead minnow, orangespotted sunfish, white sucker, and yellow bullhead.
To promote and maintain healthy fish populations, pollution and other inputs need to be controlled. Fish habitats are directly affected by water quality. Nutrient, sediment and other waste inputs can drastically alter the biological, chemical, and physical components of a lake. It is paramount to maintain if not improve the current water quality of Timber Lake through watershed management to preserve this fishery for future generations to enjoy.
