DeCLINE IN CREDIT RIVER BROOK TROUT Distribution
Maps of Brook Trout Distribution in the Credit River Watershed show a dramatic decline in Brook Trout habitat and population over time. The deterioration of Brook Trout population is likely due to the degradation of habitat from the alteration of streams, dam and pond building, urbanization, inadequate stormwater management and sewage plant discharge. The decline in Brook Trout population indicates reduced water quality in much of the watershed.
The maps were compiled by Trout Unlimited Canada using geographic spatial data, historical records and professional advice from fishery specialists and conversation experts. The purpose of maps are to help prioritize conservation efforts and protection priorities at the sub-watershed level.
The Erin Wastewater Treatment Plant will discharge into the longest remaining continuous stretch of Brook Trout habitat in the Credit River Watershed.
