Mamquam River stranding sensitivity mapping and method for estimating fish stranding / [by] K.L.C. Munn, G.C. Dare, H.D. Klassen.: Fs97-4/3102E-PDF
Hydroelectric projects can increase fish stranding due to emergency shutdowns that rapidly dewater fish habitat. Other factors affect the river’s natural susceptibility to stranding, primarily cross-section slope and substrate composition. We mapped sites of varying stranding risk along the Mamquam River based on these characteristics. We conducted transect surveys within high risk sites measuring slopes and estimating percent substrate composition and embeddedness. We developed a fish stranding estimation tool that approximates the total number of fish stranded along the Mamquam following emergency shutdowns. Our map and tool can be used to target high priority areas for fish salvage operations and calculate systemic fish mortalities during emergency shutdowns. In addition to estimating the total number of fish stranded, the tool could also be useful in influencing decisions on ramping guidelines, and powerhouse operation practices.
