I don't know if my answer is relevant anymore, but there are at least rainbow trout in Chapman's. They stock fish every year but last year the reservoir was drained to kill off pike and fix a leak in the damn. So I'm told. You can check for information by asking the Finger Rock Fish Hatchery of Yampa Colorado or call Colorado Parks and Wildlife in Steamboat Springs Colorado. The reservoir is wonderfully full of water now and the fish are plenty. (Didn't catch any but seen a bunch while swimming)
Not anymore it was drained last year
