In November 2015, the Bow River Chapter (BRC) of Trout Unlimited Canada conducted its first annual Brown Trout Redd Survey of the Bow River. The project was initiated to acquire baseline and trend through time data, as well as to supplement data from similar surveys completed on the Elbow and Bow Rivers by other organizations including Calgary River Valleys.
On November 7th and 8th of 2015 a group of three Crew Leads and up to five volunteers per crew surveyed 21.2 km of the Bow River, between Graves Bridge on Glenmore Trail to Policeman’s Flats. Survey methods included physical observations for redds either from three rafts, floating along river left, mid and right in tandem, or by foot with travel limited to on top of the banks.
