Rainbow Trout

Habitat:  Look for rainbow trout around boulders, logs and undercut banks.  The rainbow often uses deep runs and areas with overhead cover as potential feeding areas. The rainbow also prefers swift moving water and, as with many stream dwelling fish, orients themselves into the current to wait for insects to drift down.

Characteristics:  Slightly forked tail fin covered with small dark spots.  Dark olive color along back and broad reddish or pink stripe along side.  Silvery white belly and 10 to 11 rays on anal fin.
