  • Done 2008-2009
  • Adaptive management is a systematic process for continually improving management policies and practices by learning from the outcomes of operational programs. Apply Adaptive Management in NPDES Permit cycle Re-evaluate the resource to guide the next x years of implementation
  • Water Quality has significantly improved since 1983 Clarity has improved dramatically since 1993 TP & Cl-a have stayed about the same
  • 15 years of data The plant community is strongly contributing to benefits in WQ Prevention= of flipping into turbid state Lake association plays strong role
  • 2009 had three actions scheduled 1. Treatment 2. Plant Survey 3. Core samples to analyze substrate
  • Native plants are becoming more prevalent
