Puma Hills River Ranch contains 2.5 miles of Tarryall Creek along Park County Road 77 north of Lake George. The riparian community associated with Tarryall Creek provides high quality habitat for mule deer, elk, waterfowl, and breeding songbirds.
Portions of Tarryall Creek were targeted for improvements in 2007 due to impacts related to historic grazing practices, degraded riparian vegetation, lack of beaver activity, and altered flow and sediment regimes.
Funding for the Puma Hills River Ranch riparian enhancement project was provided in part by the Park County Land & Water Trust Fund.
