Lake Overholser is located in western Oklahoma County. It lies between Northwest 39th Street on the north and Northwest 10th on the south. The east boundary is Council Road and the west is roughly Sara Road. This man-made city reservoir is home to good birding almost year-round.

With its variety of habitats, birding can be good here any season of the year. Obviously, spring and fall migrations are best with the combination of migrant passerines, shorebirds and waterfowl producing the largest numbers of birds. Winter can be productive with large rafts of ducks, gulls and cormorants, especially during iceover events.

The best vantage points for waterbirds on or over the lake depends on the time of day. In the morning, the best viewing is from the dam, the island, the north shore or the coffer dam. In the afternoon, viewing is better from the west side road, the new park at Northwest 23rd or the west end of the dam.

For passerines and other landbirds, the best locations are the woods below the dam, the coffer dam, the north shore pullouts and the park-like areas on the east side of the lake. Shorebirding is usually not great unless the lake level is down. When the fields west of the lake have standing water, shorebirds can be abundant near the new park at and along Northwest 23rd.
