Soo River IIII, Impact


River overview, about half way between the facility and the inflatable dam.

We're looking into having Joel Brewer (a buddy-naturalist) develop a "hurt'n scale" to rate the enviro impact of participating reduction projects.

Soo River Hydro affects about a kilometer of the river. For one kilometer, the river experiences a drop in flow of up to 80% at times, but is never without streaming water. When the river is high, the project borrows about 20% of available water volume.

I'm assuming the river was low at this time.


The river is too far inland, too high up and too craggy to have any Salmon spawning in it, so no impact there. (SalmonSafe™?)

Reduced flow, as you can easily see in this picture, increases competition for water among species that drink here and since the drinking ponds are smaller, makes it easier to catch prey.

Reduced water flow also changes the erosion pattern of the rocks in the river, prossibly causing this 1k stretch to grout over time.

Whatever minerals and debris the river normally picks up, now only come loose during "high times" when the water reaches the outer banks and picks up stuff that's been sitting there.
