Information on Long Lake (Scandia)

Ordinary High Water   965.00  

100-Yr. Flood Elev  965.1 (District,10-day snowmelt) 

Long lake is a 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 exceed MPCA shallow lake standard of (60mg/L), and the lake is therefore listed as impaired.  In 2007 the lake was better than the MPCA shallow lake standard of 1 m for Secchi depth transparency and has an improving trend for this parameter.  Future development of this lake could further impact the lake and downstream resources and is undergoing focused watershed management.
