Discussion – Guiding Questions

  Is the current on-lake research and monitoring effort adequate to evaluate the consequences, if any, of remedial land management strategies on lake productivity?

  Is the current on-lake research, monitoring and modeling effort adequate to detect and predict potential changes in the status of Lake Winnipeg due to zebra mussels? (Bythotrephes? Other stressors?) Should nearshore parameters be considered in the current suite of eutrophication indicators?

  How can the LWRC further enhance the capacity of its Science Program to facilitate both offshore and nearshore research and monitoring on Lake Winnipeg?
