  1. Pine Lake Restoration Society Planning – 2010 and Forward

  2. History • Significant transition in Board membership and involvement over the last few years • Focus on the single critical asset – Pine Lake Hypolimnetic Withdrawal System • Monitoring Lake Water Quality through AB Environment and Alberta Lake Management Society

  3. What We Know • Weed growth in Pine Lake has slowed as a result of the withdrawal system’s preferential removal of high nutrient water • Operation of the withdrawal system has had a positive impact on water quality from a weed growth perspective • However, • Filamentous algae remains a significant and frustrating issue for those who enjoy recreational use of the lake • AB Env suggests the algae blooms are catalyzed by spring run off from high nutrient up stream areas

  4. What We Need To Do? • 2010 - continue to: • Effectively operate the hypolimnetic withdrawal system • Monitor and report on lake water quality • 2010 - start to: • Understand localized water quality issues – ex. areas where cattle still watering on lake • Evaluate the quality of streams feeding the lake and relative impact on lake water quality • Evaluate options for up stream water treatment project(s). Identify high priority project and associated scope. • While we wait for upstream projects expected to decrease algae growth: • Work with the County to support costs for disposal of algae removed from the lake • Evaluate in lake treatment options with input from RDRWSA and AB Env • Future: • Fund raise as required – grants, corporate sponsors, etc. • Implement / operate / monitor up stream project • Implement short term in lake treatment options (if viable)
