Lake Thunderbird is a reservoir located in Norman, Oklahoma. The lake was constructed between 1962 and 1965 for the purpose of providing municipal water to the nearby communities of Del City, Midwest City and Norman. It is formed by an earthfill embankment 2,200 m long and up to 44 m high on the Little River. In addition to being a source for drinking water, Lake Thunderbird's secondary uses include numerous recreational activities, which fall under the jurisdiction of Lake Thunderbird State Park. The lake is named for the Native American legend of the Thunderbird, a supernatural bird of power and strength. Many locals commonly refer to the lake as "Lake Dirtybird" due to the very murky lake water. According to local legend, the reservoir is home to a giant cephalopod cryptid called the Oklahoma Octopus.
