Below is a series of YouTube videos prepared by bDigital Professional Production of the presentations that were given on December 17th that summarize the Englishman River watershed conditions for 2014.
Gilles Wendling, P.Eng., Hydrogeolist presents on the ER Watershed and it's bedrock aquifers
Brad Rushton presents on photo point monitoring in the ER Watershed
Shawn Stenhouse, B.Sc Biology, presents on stream flow monitoring
Julie Pisani, Regional District of Nanaimo presents on the community watershed monitoring network
As part of the Watershed Health and You program, Shelly Creek was subject to an instream fish habitat assessment summer 2014. Volunteers were trained by Fisheries Biologist, Dave Clough, in the Urban Salmon Habitat Program (USHP) methodology. (USHP was developed in the late 90s by the Ministry of Environment – Fisheries for new stewards as a way for them to assess their urban streams before launching into restoration activities.) Shelly Creek was assessed in 1999 by MVIHES members using the USHP so this provided a great opportunity to replicate the study in 2014 and get new volunteers to assess this important tributary and determine the condition of the habitat after 15 years.
Here are some of our findings:
There was a 50% decrease in pools –probably a result ofstream erosion causing sediment to move downstream and filling up pools where fish reside in low flow periods
We found less Large Woody Debris available for fish to act as complex cover – the debris probably gets cleaned out to prevent flooding of private properties
Significant increase in the amount of fine sediment covering the bottom of pools – fish do not survive in streams with muddy substrates
Decrease in gravels – Salmonids need gravels for spawning
Significant increase in erosion of stream banks during high winter flows – causes infilling of pools downstream
A High number of obstructions to fish passage during low flow periods – mostly wood and root jams with gravel plugs
Alterations to the stream were largely due to placing of riprap and removal of woody debris
Stream temperature was high in upper reaches in spite of excellent riparian cover
A Report will be compiled for MVIHES by Peter Law
