Presentation Transcript



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.


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.


Water quality

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.

Bank stabilization burrowing
Bank Stabilization/Burrowing improve water quality.

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

Population dispersal
Population & Dispersal improve water quality.

  • 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


Educational opportunities
Educational Opportunities improve water quality.


Volunteers

  • Creek Cleanup

  • Paddlers Cleanup

  • Willow Planting

  • Beaver Docents
