South West Wrights

South West Wrights


Project Description:

 We are planning on installing armor rock along a section of eroding river bank on the South West branch of Wrights River in Antigonish. We will also be installing two rock sills to facilitate the digging of pools. This section of river has been identified  by our group as a source of sediments in the South West Wrights River, we believe this has lead to a decrease in spawning habitat.


Need for the Project:  What habitat issues will the proposed project address?

The main habitat issue being addressed by this project is stream bank erosion. This section of river flows along agricultural land and this is likely the cause for erosion. The new land owner has fenced his livestock out of the stream and off the river bank. The amount of sediments entering the stream from this erosion source was likely reducing the survival rate of salmon and trout eggs, the erosion also resulted in loss of water depth.
