MPCA beginning water quality monitoring field work in the Otter Tail River Watershed. (2016, May 13). Minnesota Pollution Control Agency.

This short news release gives some basic information about the Otter Tail River Watershed and what the MPCA will be doing over the next several months and/or years. This short 508-word press release gives an overview of the activities involved with watershed monitoring to the public.




Berg, J., et. al. (2015, March). Minnesota Nitrogen Fertilizer Management Plan (Publication). Retrieved September 18, 2017, from Department of Agriculture website: http://www.mda.state.mn.us/nfmp

The Nitrogen Fertilizer Management Plan (NFMP) was created to reduce nitrates in groundwater, especially in areas where the groundwater exceeds the drinking water standard of 10ppm or is expected to increase to that level. The 1989 Groundwater Protection Act was the main stimulus for the NFMP, to prevent degradation of groundwater in Minnesota. This document begins with an explanation of the issue and where and why it is relevant. It relies mainly on BMPs that are effective for each region to produce nitrogen reductions. However, there is a regulatory option if adoption rates are low. Further updates are possible as comments continue to be received and assessed.




Wilkin Soil and Water Conservation District, Wilkin County, & Minnesota Pollution Control Agency. (2007, February 14). Lower Otter Tail River TMDL Implementation Plan. Retrieved September 15, 2017, from Minnesota Pollution Control Agency website: https://www.pca.state.mn.us/water/watersheds/otter-tail-river

The Lower Otter Tail River exceeds the turbidity standard and reductions are needed during high and moderate flows to reach sediment reduction goals at the mouth of the Lower Otter Tail River. The watershed is largely agriculture (90%) so implementation practices will be aimed at preventing filed and stream erosion. These practices include Buffer strips, side inlet structures, and stream barbs. The implementation schedule is divided into two phases, with the first phase happening through 2009. The second phase will evaluate results from phase one and make changes as necessary and is expected to go through 2017. There is also a component for education and outreach. Included is an estimated budget for each practice and incentive cost per unit of area installed (area unit differs between practices).



Otter Tail Watershed Improvement Project. (n.d.) Big Pine Lake Association.

This short proposal outlines the basic goals, approach, and funding for a project to reduce water pollution in Big Pine Lake. The proposal is based off results from a 1991-1992 Lake Assessment Program study. It includes establishing regular monitoring, conducting feedlot inventories, and determining best management practices for land use in the lakeshed.
