Large Scale Lake Planning
On 31 August 2009 a sediment core were taken from near the deep area. In summary, the sediment core indicates that Poskin Lake was historically an eutrophic lake. Although phosphorus levels at the present time are in the range of 50 ug L-1, they were likely not much lower prior to the arrival of European settlers 150 years ago.

Poskin Lake Association is sponsoring a three-phase project to assess watershed, water quality, shoreline, and aquatic plant conditions; determine nutrient loads and model lake response; develop watercraft inspection and AIS monitoring programs; distribute and analyze a sociological survey; coordinate stakeholder participation and planning; and develop a lake management implementation plan. The final deliverable will be a single lake management plan that includes methodologies, results, and management alternatives discussion with an implementation plan. Interim deliverables for each phase include a progress report with results, including maps, spreadsheets, and other data collected during the given phase.
The specific Phase 2 (LPL-1271-09) project tasks include: 1) Spring and summer whole lake aquatic plant point-intercept survey; 2) Shoreline inventory; 3) Watershed evaluation with nutrient loading calculations; 4) Top/bottom paleoelimnological core; 5) Water level management and zoning/ordinance review.
Special Conditions: 1) WDNR's Aquatic Plant Management in Wisconsin guidance should be followed for point-intercept survey monitoring and aquatic plant management plan development; 2) Draft public surveys and shoreline inventory methods must be reviewed and approved by the Department before being initiated.
