LAKE WATER AND NUTRIENT BUDGETS REPORT Buffalo River Watershed

This report addresses the water and total phosphorus (TP) budgets created for lakes in the Buffalo River Watershed (BRW) as described in Task 10 of the Minnesota Pollution Control Agency (MPCA) contract #B55092: Buffalo River Watershed Approach Plan Phase 2. Results of these budgets will be used to inform modeling to be completed during the next steps of the BRW Approach project. Budgets were created for the five lakes in the Sand-Axberg Chain of Lakes in the north-central portion of the BRW. In addition, water and TP budgets were created for each of the five “example” lakes developed under Task 9 of this project (HEI 2011a). Herein, we describe the data and methods used to compute water and TP budgets for the five specific and five “example” lakes during the years 1997-2010.
