Is it true that channel catfish do not spawn in Idaho?

I've heard that catfish must be stocked to maintain populations in this state. I'm particularly interested in Boundary and Bonner counties.


Channel catfish do successfully spawn in a few waterbodies throughout the state, however, most waters in North Idaho do not maintain the minimum water temperature long enough (>75 F) for reproduction.
Channel catfish are a relatively long lived fish ~15 - 20 years and grow rapidly when young.  Adults reach sexual maturity at about 3 years of age.  Males prepare nests and attract females from long distances to spawning locations.  Once spawning is complete the males guard the nest until juvenile fish are mobile and can actively feed on insects.
