Not by the dam. The gravel ponds are listed as "Gravel Ponds" on the Chatfield park map. They are on the southwest end of the park. I think there are 4 ponds there if I recall. One is quite large - the one I fished, the others are small. I've fished them in the summer several years ago and never caught anything there. Supposedly they contain perch, bass, crappie. Confirmed the perch on the ice fishing trip.
