Shel,
Only the flowing waters and Burnstick Lake contained pike.
Every other lake only had minnow populations.
These lakes were stocked with invavsives from somewhere.
Cow Lake does contain pike, most have died due to winter kill. Catch rates are lower by far.
What a trade - from 15 lb. rainbows to 2>4 lb, pike and tiny perch.
To rotenone Cow Lake would cost upwards of a million dollars. To do other lakes in the area may add another million.
Time for a perch killing tax in fishing licenses? $20/year/angler would do Phyllis and Tay the following year Struble and Twin.
