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. About 12 species now occur in Grenadier Pond, including small numbers of top predators such as bass, and more abundant smaller fish such as pumpkinseed and bluegill.

Fishing

Fishing is currently permitted in season along a designated section of the Grenadier Pond shoreline. Grenadier Pond is a protected natural area. If you fish here, be sure you know and follow fishing regulations and catch-and-release techniques.
