Riverkeepers: Brown Trout Redd Survey
As you wade the river, you think all those shiny spots in the gravel bottom are trout redds — where fish lay their eggs each Fall.
But maybe not! Disturbances caused by geese, ducks , muskrats and even mink often trick the angler.
Every October since 1968, Gerry Lake has studied the spawning habits of Brown trout on the North Branch. And he knows his redds.
Follow along with Lake, David Triezenberg and Dennis Schoberth as they identify real redds and record their GPS coordinates, dimensions, depth and whether they have adjacent cover. All this information will be used as researchers install better cover for spawning trout.
The Riverkeepers series on AuSableTrout.com explores the work of organizations and volunteers who do good work for Michigan's northern rivers. We hope you'll consider contacting one of these organizations to join or volunteer. And if you have a good 'Riverkeeper' idea, please let us know at info@AuSableTrout.com.
