1983 Watershed-Lake Assessment. (April, 1984). Instrumental Research, Inc.

This assessment was used to determine the existing condition of the lakes located along the Pelican River and identify any corrective measures needed. Lake samples were collected for nutrients and water clarity. Sediment core samples were collected to determine sedimentation rates. Management practices include determining and reducing upland nutrient loading sources, modifying some marshlands in the watershed to hold more nutrients and sediment during severe storm loading, preventing backflow of more polluted lakes into more pristine lakes, and lake aeration treatment.



Reedstrom, D. C., and Carlson, R. A. (1969) A Biological Survey of the Pelican River Watershed Becker, Clay and Otter Tail Counties. (Minnesota Department of Conservation, Division of Game and Fish). Special Publication No. 65

This report outlines numerous surveys on multiple lakes in the Pelican River Subwatershed. Summaries of the surveys are provided for some of the larger fish lakes and the Pelican River and Sucker Creek. It includes information about wetlands in the watershed, including size and depth of the wetland. The report then discusses water quality in the region and concludes with general recommendations. The recommendations include lakeshore and streambank zoning to restrict the impact of development on lakes and other natural resources.



McComas, S., Hecock, D., and Nustad, R., Wilson, B. An Updated Diagnostic and Feasibility Study for Lake Sallie, Detroit Lakes, MN. (November 1996). Funded by the Pelican River Watershed District.

This study was designed to evaluate new data collected since the 1993 report and prepare a revised implementation plan. Improvement strategies for Lake Sallie include reducing external phosphorus loading from Lake St. Clair and enhancing biomanipulation effects in Muskrat Lake to reduce phosphorus loads from Ditch 14. A summary of proposed projects includes alum treatments, a winter aerator, aquatic plant harvesting, and wetland source study projects. A budget and more detailed description of data results and implementation plan details is also included.


Steven, H., Renard, P., Kirsch, N., & Enblom, J. (n.d.). Biological Survey of the Otter Tail River (Special Publication #137).

A survey of the Otter Tail River for fish and other wildlife habitat was performed in 1978, 1979, and 1980. This survey included electro fishing, macroinvertebrate collection, and vegetation surveys. As a result of the surveys five conclusions and recommendations were suggested: 1. Increase land use conservation of forest and other beneficial upland practices. 2. Revise the Hoot Lake Power Plant appropriation permit to encourage water conservation. 3. Install stream gauges upstream and downstream of Fergus Falls to track water flow changes. 4. Stock smallmouth bass in sections of the Otter Tail River. 5. Create a reservoir management plan for Lake Orwell.



Sether, B. A., Berkas, W. R., & Vecchia, A. V. (2004). Constituent Loads and Flow-Weighted Average Concentrations for Major Subbasins of the Upper Red River of the North Basin, 1997-99 (Scientific Investigations Report, Publication No. 2004- 5200). Retrieved September 15, 2017, from https://pubs.er.usgs.gov.

From 1997 to 1999 the USGS collected water sampling data, including concentrations and flow weighted averages, at 11 sites in the Red River Basin. In general concentrations increased downstream, but median concentrations for most constituents were less than existing water quality standards. This data was used to determine which sub-basins contribute the most pollutants to the Red River. Results were generally inconclusive, but the Otter Tail River Basin generally contributed the least pollutants and flow (during high flows) to the Red River.
