Msd-
What I Have Always Done Is Park In The Parking Lot In Front Of The Fish Hatchery And Walk Down The Road To The Kid/handicap Section Of Hatchery Creek. From There, I Just Walk Past Where The Water Is Released Through A Covert And Continues Down To Meet Up With The Main River (you'll See Where The Water Drops Down And Out The Covert About 15ft Below The Trail Above).
The Browns And Bows Spawn All The Way Up To That Point Where They Can't Go Any Further......you'll See The Fish As You Walk Above On The Trail......it Gets Your Heart Pumping! They Average From 16-24 Inches....and Sometimes Bigger! Lots Of Fun...especially On A Fly Rod! Hope This Helps Answer Your Question. If You Have Anymore, I'd Be Happy To Help Out! Keep Your Line Tight!
