Recent Lake Survey Summaries

Here are preliminary summaries of recent sampling not yet posted on LakeFinder, or survey types not found there. Different gear target fish species and sizes quite differently; for example, northern pike and walleye are better caught by gill nets, while bluegill are better caught with trap nets. Values of black crappie might be from either net type. Spring ("ice-out") sampling targets northern pike, walleye, or muskellunge. Our net-based surveys under-sample largemouth bass; electrofishing better evaluates bass abundances and size structures, but requires extra sampling with different equipment.

Spring Sampling 2014

Soon after ice-out, we checked Medicine Lake walleye to see size and age composition of larger adult fish. We also measured the northern pike and largemouth bass captured. Results are from 36 total net locations.

Lake
(County)
Date
Fish Species Number Average Length (in) Max. Length (in)
Medicine Walleye 50 21.0 27.6
(Hennepin) Northern Pike 173 22.9 35.0
4/17-22 Largemouth Bass 27 15.9 19.8

 

Winterkill Checks 2014

The cool conditions of spring 2014 allowed us to do some assessment of winterkill impacts.  Summary information is below.
Eagle Lake (Carver Co.):  Sampled 4/25/14-- entire shoreline electrofished.  Only two golden shiner captured and one larger-sized fish too far out of range to ID.  Lake was stocked in May at 2.4 times its normal walleye fry quota.  If timing and fish survival allow, a portion of these walleyes might be harvested in fall 2014 for local fingerling-stocking needs.

Mitchell Lake (Hennepin Co.): Angler report late May 2014   Despite winter 2013-14 oxygen readings dropping to the low-2 ppm range, no dead fish were reported.  In late May, a lake resident sent images of adult northern pike, largemouth bass, and walleye caught from the same location, indicating at least some adult gamefish survival.
