Park situation

Daily Entrance permits are available for purchase at the Automated Pay Stations on South CR 31 and West CR 8E, near the entrance station gates. The automated pay stations accept credit and debit cards only. Cash or checks will no longer be accepted at the self-service automated pay stations.

Fishing conditions

Fishing is a bit slow as of late, possibly due to major fluctuations in the water level at Flatiron. Visibility tends to be more difficult when water is being let in and out. Try bright colored powerbait or scented bait. Salmon eggs and garlic scent have had some success. You can check out water levels at http://www.usbr.gov/gp-bin/arcweb_flaresco.pl.

Cheyenne Day Use fishing access is now open and accessible from County Road 31, just past the entrance gate.

The limit for trout is four (4) per person with no size requirement.

A large herd of elk has been frequenting the reservoir. Be aware that wild animals are very unpredictable and should be enjoyed from a distance. Wildlife will often congregate near the roadway. Use caution when driving in areas that have a lot of animal activity. Be sure to lock your food up and never feed the wildlife.

Our resident geese appreciate responsible disposal of fishing line, hooks, and other trash.
