- Claflin, T.O. 1977. Lake Onalaska Rehabilitation Feasibility Study.
Report to Lake Onalaska Rehabilitation District. 43pp. (pdf)
Summary: Found Lake Onalaska already highly eutrophic with a loss of 31% of its volume to sedimentation since its creation in 1939. There was no significant nutrient input from shoreline residents. Forecast rapid encroachment of macrophytes to the (then weed-free) central portion of the lake, followed by a transformation to a marsh-like state. note: of the 4 potential remedial actions, only the second (hydrologic controls on input flow) was deemed feasible and effective. This remedial action was partially implemented in the early 1990s with the construction of closing dams across 4 principal inflow chutes (No-name, Gibbs, Goose, and Sommers chutes).

following mechanical harvesting of aquatic macrophytes. unpublished final report, Viterbo College Dept. of Biology. 82pp. (pdf))
Summary: Aquatic vegetation was mechanically harvested during the summer of 1979 in three study areas. Harvesting reduced plant biomass for about one week, but the areas were rapidly repopulated. The number and biomass of invertebrates did not differ between harvested and control areas.

- Shoreland District Zoning Brochure from La Crosse County
- 2011 Land Use Allocation Plan (LUAP) document (link to pdf), a document used to guide federal agencies in determining what types of public uses should be allowed on federal lands along the upper Mississippi River.
- 2004 Upper Mississippi Environmental Pool Plan which contains maps and descriptions of what river managers and the public have identified as the desired future habitat condition toward which resource agencies and other river interests can strive. The plans serve as a guide for individual agencies as they carry out their respective missions and seek funding to do so in a way that insures environmental sustainability. The plans are considered to be an environmental concept that the River Resources Forum can reference when considering future projects and activities brought forth by member agencies.
