Four Mile Creek Site 1 Reservoir is a 188-acre (0.8 sq km) impoundment located near El Reno, Oklahoma. Constructed in 1966 as a flood control project, the reservoir provides both flood protection and recreational opportunities. The lake features 170 surface acres of water and is surrounded by 333 acres of open land.

The reservoir was built by the City of El Reno with an additional 700 acre-feet of water storage designated for recreational use. Water activities on the lake include boating, water skiing, and jet skiing.

The lake's primary purpose remains flood control, protecting 750 homes in El Reno as well as 35 farms and ranches in the surrounding area. Red Rock Canyon State Park is located within the vicinity, offering additional recreational opportunities for paddlers looking to extend their visit to the area.

Nearby Lake El Reno (0.5 miles away) and Lake Rolla (2.0 miles away) provide alternative paddling options if water levels or conditions are unfavorable. The reservoir is situated in an area where air temperatures typically range from highs around 50°F (10°C) to lows around 28°F (-2°C) during cooler months.

This is part of a larger watershed management system, with the dam serving as the only flood control structure on Four Mile Creek. While the reservoir offers recreational opportunities, paddlers should check local regulations regarding water access and permitted activities before planning their trip.
