Good News from the DNR:

WI DNR Fisheries is conducting a comprehensive fish survey of Clark Lake this year/2026, which will likely consist of 1) early spring fyke netting, 2) immediately after this netting, we’ll conduct nighttime electrofishing, 3) later spring electrofishing, and 4) fall electrofishing.

DNR staff set survey nets in Clark Lake on Sunday April 12.  The flags that you mentioned, are attached to survey nets.  These flags are used as an identifier and so that fisheries staff can lift nets to collect and sample captured fish. 

This survey is being led by DNR Senior Fisheries Biologist Logan Sikora and DNR Fisheries Biologist Jacob Steckmesser.
