- Lake Richland Chambers Reservoir -

Native pondweeds are abundant in Big Cedar Creek and along the south bank of the Chambers Creek arm. Hydrilla is scattered along the south bank of the Richland Creek arm from Midway Marina west to the railroad trestle and from 7L ramp south to Pin Oak Creek. The old Trinity River levee forms a crescent-shaped underwater structure between the confluence of the Richland and Chambers creek arms and the dam.
