The DNR conducted electrofishing on Monday night, October 12, 2020.
Initial report was disappointing but not devastating. The crew pulled 15 "young of year" walleye. YOY are walleye hatched this year. Fifteen is a small number but it is slightly better than last year and it is all the result of natural reproduction as there was no stocking this year.
That's the good news. Of course, weather, etc. can be a factor but we've had a pattern of low results the past few years so there must be validity to the results. Hopefully, stocking can resume next year. Also, it is important that those 17-25" walleye be released to the lake rather than to the frying pan.
If I get any other insights, I'll share them. John Harris

Historic Results Gill Netting & Electrofishing on Lake Washburn
2017 Netting Results Report/Comparison -
Submitted by John Harris
Lake Washburn is a beautiful body of water. Whether you are here for a day or are a year-round resident, there are many ways to enjoy activities on this lake, including angling. At least sixteen species of fish have been identified inhabiting our clear lake water. Small and large mouth bass, walleye, northern pike, crappie and, pan fish are included in the array of fish.
If you enjoy fishing, you are likely to be successful in catching something. If you are fishing for walleye, well that’s a little tougher. Our walleye tend to be fewer in number but larger in size. The Washburn Lake Association has been collaborating with the Minnesota DNR for several years, trying to improve the walleye population. There are two primary issues with respect to being successful in this quest… natural walleye reproduction is low and so is the primary food fish, perch. Without an adequate supply of perch, young walleye become a primary food source for most other fish. There are no catch and release requirements on Washburn but all sportsmen are encouraged to quickly release any walleye over 17” as fish that size are generally females and the prime breeding stock that fuels natural reproduction. Anglers are also encouraged to keep those smaller 15” or so northern that love to feed on small walleye. The filets from these “hammer handles” can make an excellent meal.
The DNR regularly tests Washburn to determine the quality of the fishery. This includes electro-fishing in the autumn and occasionally, gill netting. Gill netting was most recently done in the summer of 2013 and again in the summer of 2017. A chart taking a quick look comparing the results of the two tests follows. Note that pan/sunfish are not typically caught in the gill netting process.
ANNUAL NETTING ON WASHBURN.......
We have now completed the plan developed with the DNR to manage the walleye fishery on Washburn. The plan included stocking walleye every other year and then testing results via electrofishing each Sept and netting every other Aug. The final netting's were completed August 14th thru 18th, 2017. This is a critical part of the process and the results will be a big factor in future fisherie management planning.
The Nets used are 250’ in length. The nets are divided into five segments, each 50’ long. The segments vary in the size of the openings ranging from ¾”, 1”, 1 ¼ “, 1 ½ “ & 2”.
This is designed to help avoid a catch of a lot of fish in any one size category. Most of the fish caught are dead upon retrieval although some live… I observed a northern being released alive today. Overall, the nets cover a very small portion of and have minimal impact on our fishery.
Fisheries - Stocking & Testing
The DNR has conducted electrofishing on Lake Washburn.
Electrofishing is used to try to gain insight into the young of year walleye population including numbers and to whether the fish are from stocking or natural reproduction. A boat mounted generator is used to induce electrical current into the water that stuns the fish, allowing fisheries workers to net the fish for placement in live wells. Most of the fish caught by electrofishing recover rapidly and are promptly returned to the water after the necessary biological data is recorded. The results for Washburn was catch rate for young-of-the-year was only 5.9/hr. The frylings looked okay when stocked but apparently didn't fare well thereafter.
