  1. Beaver Subcommittee Report

  2. The original Dam height was assessed at 7 feet.

  3. Skip Lisle was hired to install a flow device to regulate pond height.

  4. Since January the Dam has been successfully maintained at a lower height. During hard rains the dam has washed out naturally and the beavers have rebuilt.

  5. The hydrology section of the report examines several possible solutions for maximizing flow through the creek. A combination of flood wall extension and bank overflow was agreed to be of greatest value in terms of cost and system benefit.

  6. Beaver dams act as a natural filter and have been shown to improve water quality. Concerns remain about stagnation/oxygenation. The report outlines a proposal for vertical profile testing during the summer months in which there is low flow using volunteer and student effort. Water Quality

  7. Creek Walk

  8. Bank Stabilization/Burrowing Concerns have been raised about beavers burrowing in the east bank. Muskrats also tunnel in banks and along dams. This is a drawing of a typical tunnel from a muskrat management article http://wdfw.wa.gov/wlm/living/muskrats.pdf

  13. Population & Dispersal • Beaver Populations Grow Slowly • Adults are monogamous; breed once per year • Kits remain with parents for 2-3 years • Highly Territorial: One colony/2-4 miles • Dispersers travel 2-30 miles

  14. Educational Opportunities

  15. Volunteers • Creek Cleanup • Paddlers Cleanup • Willow Planting • Beaver Docents

  16. Project Costs

  17. Grants & Funding

  22. Addressing the Problems Protection from flooding Control burrowing Prevent Erosion Monitor Water quality Reaping The Benefits Management Strategy

  23. Relocation • Use only Hancock traps • Hire skilled expert • Assess relocation site • Relocate in Fall • Know risks
