Moltzan, Deb. Becker County Septic Inspection Plan. (2012). Received 4/5/18

This powerpoint presentation outlines the septic inventory program run by Becker County. Increased water quality concerns initiated this plan staring in 2007 to reduce the occurrence of non-compliant systems, especially systems with an imminent threat to health. Lakes were initially chosen by trophic index value, the lakes with higher values were prioritized. It is generally a one- to two-year process, unless county attorney action is required. From 2007 to 2010 about 200 noncompliant septic systems have been upgraded or corrected.



Hecock, R., D. Diagnostic and Feasibility Study Goals, and Management Alternatives for Lake Sallie and Detroit Lakes Pelican River Watershed. (December 1993).

This study looks at Lakes Sallie and Detroit for improvements in water quality. It starts with background and description of these lakes. Recommendations for these lakes include upland BMPs, stormwater improvements, wastewater improvements, alum treatments, and vegetation removal. Detroit Lake will be protected to limit further degradation, preventing the trophic status from going above 50, the eutrophic condition boundary. Internal phosphorus and runoff are the main sources and concerns for this lake. Lake Sallie has a very low trophic status and will be restored to a trophic level of 50. The main concerns for Lake Sallie are eliminating mid-summer episodes of high loading from internal sources, runoff, and releases of nutrients from upstream sediments. See the Diagnostic and Feasibility Study here and an updated version here.


Lower Otter Tail River, Wilkin County, Minnesota Section 1135 of the Water Resources Development Act of 1986 Project Management Plan. (DRAFT January 2017). Army Corps of Engineers.

The Army Corps of Engineers has developed a draft project management plan for the Section 1135 feasibility study for the Lower Otter Tail River. The Lower Otter Tail River is impaired for turbidity and the goal of this project is to reduce turbidity by stream re-meandering and reconnecting to old oxbows. Turbidity can reduce the survivability of certain bugs and fish, clog spawning habitat, and transport nutrients or other harmful chemicals downstream. Connecting to old oxbows can reduce the erosive power of the stream and cause more sediment to settle out of the water. The project management plan includes a list of the project delivery team, a schedule of tasks, and a budget divided by discipline. Included here are some example pictures of the efforts completed to determine the feasibility to reduce in stream erosion and reduce the impact of channelization.

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).




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.
