Fish of High Park

The fish community of Grenadier Pond has undergone considerable change over the years. With the connection to the lake gone, the fish are locked into the pond and rely on it for all of their lifecycle requirements. Currently about 12 species occur in Grenadier Pond, including small numbers of top predators such as pike and bass, and more abundant smaller fish such as pumpkinseed and bluegill. 


Conscientious anglers can help maintain a balanced population at Grenadier Pond by following sport fishing regulations and learning how to properly catch and release fish. If you fish here, please fish responsibly.
