Information on Fish Lake

Ordinary High Water   951.00  

100-Yr. Flood Elev 954.2 (FEMA) 

Fish Lake is a long, shallow lake with poor water quality and limited development.  The lake is tributary to Jellum’s Bay which in turn outlets to Big Marine Lake.  In-lake phosphorus concentrations commonly double the MPCA shallow lake standard of (60mg/L) and the lake is therefore listed as impaired.  In 2008 the lake did meet the MPCA shallow lake standard of 1-m for Secchi depth transparency and has an improving trend for this parameter.
