Park Highlight
Explore the Water
St. Vrain is a nature- and people-friendly park offering 236 acres of water (not including wetlands and rivers), split among several ponds. Come boat, walk on the trails, fish or just enjoy the natural beauty. Anglers will find many opportunities to seek out their next big catch from the modern, accessible fishing piers. The ponds are stocked several times a year with selected species.
Blue Heron Reservoir
Gas powered motors are permitted on Blue Heron Reservoir along with hand-launched vessels that must be operated at wakeless speeds. There is a boat ramp, trailer parking and restrooms available. Catch and release bass fishing is popular.
Ponds
Hand-launched vessels that are hand or foot propelled or with electric trolling motors, along with inflatable devices with two or more chambers, are permitted on all ponds. Twelve species of fish can be caught.
Reservoir and Pond Facilities
Facilities
Blue Heron Reservoir has a boat ramp and parking for boat trailers. The boat ramp is located on the northeast side of the reservoir and accessed from 24 1/2 Road.

There are also stone fishing platforms located in Pelican, Mallard, Sandpiper, Bald Eagle and Coot ponds. These fishing piers are available for all visitors to use, but please be courteous to your fellow anglers and allow space for those with disabilities or limited mobility.

Bowfishing for carp, suckers and northern pike is permissible with a valid fishing license. Bowfishing or gigging is allowed for bullfrogs as well, during the legal season.

Colorado ANS Inspection SitesEurasian watermilfoil
Eurasian watermilfoil is an invasive aquatic plant that has been found in Mallard Pond. Before you take watercraft or equipment into a pond, check it thoroughly for mud and plant particles that could introduce new unwanted species into our ponds. Then, after you remove equipment from the water, check it again and clean off any plant debris to be certain you don’t carry anything to your next fishing location.
