PUB-SS-1034 2007. Final Report. "A sediment core was collected from the lake on 28 September 2006...The core was dated by the 210Pb method and the CRS model used to estimate dates and sedimentation rate. The diatom community was analyzed to assess changes in nutrient levels and changes in the macrophyte community and geochemical elements were examined to determine the causes of changes in the water quality."
Grant Awarded
The Big Round Lake Protection and Rehabilitation District will conduct a project to analyze a sediment core from the deep area of Big Round Lake. The analysis of this sediment core may help to evaluate the history of water quality in the lake and possibly help in making the following determinations: 1) Determine impact of installation of the dam on the lake's ecosystem. 2) Determine changes in nutrients during the last 130 yrs. 3) Determine if the frequency of algal blooms has increased during the last century, and 4) Determine if the macrophyte growth has changed during the last century.
Project deliverables include a final report detailing the findings of the core analyses and a listing of any past significant water quality or lake ecosystem "changes" that are revealed from this analyses. The project results will be disseminated to the public by newsletter(s), public meeting(s), and local newspaper articles.

Monitor Paleocore
One core collected from Big Round Lake with a piston core. Diatom analysis was done.
