On June 22nd fisheries biologists in the Downeast Region opened the fishway at the West Grand Lake dam in Grand Lake Stream to allow passage for landlocked salmon as well as brook trout. Grand Lake Stream is a hugely popular salmon fishery and as spring passes and summer arrives, water temperatures rise in the stream which means salmon and brook trout seek the cool deep water of West Grand Lake.
As the fishway begins to fill with water, salmon and trout immediately start making their way into to the fishway, until they hit the hydraulic jump. Within a few short hours, salmon and brook trout are leaping over the hydraulic jump and into the lake. This short video shows fish navigating the fishway.
If you ever find yourself in Grand Lake Stream this time of year, make sure to stop by the West Grand Lake Dam and see for yourself how these fish migrate from one body of water to another!
