LITTLE GREEN LAKE P & R DISTRICT: LMI - Little Green Lake Alum Treatment Feasibility Study


The Little Green Lake Protection & Rehabilitation District is sponsoring a management plan implementation project with the following goals: Determine 1) Level of internal phosphorus loading; 2) Required Alum dose to reduce that internal loading by 90%, and 3) Estimated cost of completing the treatment. Project deliverables include: 1) Determine the mass of phosphorus that is being internally loaded during the growing season; 2) Determine correct alum dose to significantly reduce internal nutrient loading by 90%; 3) Determine if an alum treatment on Little Green Lake would be fiscally feasible and produce sufficient and long-term improvements to water quality. 4) Final report summarizing findings of the study. Specific project conditions: WDNR review of the draft study report; WDNR will be provided electronic and hard copies of data and reports/plans generated as a result of this project prior to submission of grantee's final payment request.
