Reference Lake and Trend Monitoring Summary for Isanti County, Minnesota

During the summer of 1998 the Minnesota Pollution Control Agency (MPCA) monitored four lakes in Isanti County as a part of our Reference and Trend Lake monitoring efforts. This monitoring effort is intended to supplement and complement data gathered through the Citizen Lake Monitoring Program (CLMP), Lake Assessment Program (LAP), and Clean Water Partnership (CWP) Program. The intent of this lake sampling effort is to: provide baseline water quality data, provide data for potential LAP and CWP lakes, characterize lake condition in different regions of the state, examine year-to-year variability in ecoregion-reference lakes, and provide additional trophic status data for lakes exhibiting trends in Secchi transparency. In the latter case, we attempt to determine if the trends in Secchi transparency are real
