Information on Hay Lake

Ordinary High Water   972.40 

100-Yr. Flood Elev.    973.5 (District, 10-day snowmelt) 

Hay Lake is in the City of Scandia. The major land use of the Hay Lake watershed is rural/agricultural.  The Hay Lake watershed flows into the Sand Lake watershed which overflows downstream through an ephemeral channel within William O’Brien State Park to Mill Stream and ultimately the St. Croix River.  Hay Lake does not have public access and the majority of the shoreland is in private ownership.  2020 land use shows most of the watershed converting to rural or large-lot residential land use.  As land use in the watershed converts to rural or large lot residential and multi-optional development, the amount of impervious surface will increase.
