Fish Stocking Activity

Fish Stocked by Species for the Last Ten Years

Year Species Size Number Pounds
2011 Walleye fingerlings 165 11.0
  Walleye yearlings 3,342 151.9
2010 Northern Pike fingerlings 800 3.5
2008 Walleye* fingerlings 1,730 160.0
2006 Walleye yearlings 560 56.0
  Walleye fingerlings 820 41.0
2005 Bluegill adults 350 70.0
  Largemouth Bass adults 100 40.0

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 06/04/2012)

INTRODUCTION

Summit Lake is a small and relatively disconnected lake located in Murray County just outside the town of Hadley. Summit Lake has a watershed-to-lake ratio of only 7.7 to 1, which means there is only 7.7 acres of upland area that drains to the lake for every 1 acre of surface water. It is one of only a few lakes in the Windom Fish Management Area that does not have an aeration system. In spite of the fact that the lake is not aerated during winter, low dissolved oxygen is not a problem other than in winters with excessive snow. This 77-acre lake is managed primarily for walleye and secondarily for northern pike and yellow perch. Summit Lake was surveyed the first week of June of 2012 with 1 gill net and 9 trap nets.

WALLEYE

Typically the DNR uses gill net catch rates as the indication to the abundance of walleyes in a lake. However, Summit Lake is a good example as to why all types of nets need to be used to evaluate the status of the fish population. No walleyes were sampled in the one gill net. However the trap nets sampled the most walleye ever recorded in trap nets on Summit Lake. Although the population is dominated by smaller fish, they appear to be abundant. It would seem the 2011 walleye fingerling stocking was successful. The average length of the walleye in the sample was only 7 inches. Although the fish are small, the abundant forage base available indicates that these walleyes may be primed for some good growth. In the interim, target the abundant yellow perch population.

YELLOW PERCH

In addition to providing a great forage base for walleye, the yellow perch fishery will likely provide some excellent fishing in the next few years. The 2012 survey documented the highest catch rate of yellow perch in both trap and gill nets. Both of these nets indicated catch rates more than 10 times the upper normal range. The average length yellow perch was 7 inches. If you are looking to take the kids fishing from shore, Summit Lake would be worth considering.

NORTHERN PIKE

There is always a chance while fishing for yellow perch that an angler could catch a northern pike. Given the size of the lake, the northern pike numbers are very respectable. Historically we have had only 1 other survey when northern pike numbers have been higher. There are currently a couple of age groups of northern pike in the lake. It appears that the 2010 northern pike fingerling stocking was successful and many fish survived. With the abundant yellow perch population as prey, it is likely the northern pike will grow fast. Lengths of northern pike ranged from 25 to 38 inches. Selective harvest by practicing catch-and-release of larger northern pike will help to sustain the population by allowing the larger fish (usually females) to spawn.

OTHER SPECIES

Historically, black bullhead numbers have been much higher. It would appear that the walleye stockings in the past may be controlling black bullhead numbers. While the black bullhead fishing from shore will provide some angling activity for the kids, the sizes of bullheads are probably not going to be worth keeping at this point.

Unfortunately, we first sampled common carp in Summit Lake in the 2008 survey. In the 2012 survey, we sampled 11 more common carp in the gill net and trap nets. Based on the length frequency histogram, it would appear there are 2 year classes. All but two of the fish sampled had total lengths ranging from 23-27 inches. The two sampled in trap nets had total lengths in the 11.5-13.0 inch range. It is unknown if these smaller fish are offspring from successful Summit Lake spawning or immigrants. Other species sampled were hybrid sunfish and white crappie.

SUMMARY

To maintain a healthy fishery in Summit Lake; we need to promote Best Management Practices (BMP's) within the watershed to help reduce nutrients entering the lake. High nutrients and sediments in a lake can cause algae blooms and reduce water clarity. Any improvements in the way of natural drainage in the watershed (non-tiled drainage to mimic natural wetland drainage) will help the fish community through increased water quality and water clarity.
