Diascund Creek[1] is the major tributary of the Chickahominy River in Virginia, part of the Chesapeake Bay watershed.

In 1963, an earthen dam was constructed across the creek above Lanexa to create a 1,100 acre reservoir for Newport News Waterworks.

In the 1960s and 1970s, the subdivisions of The Colonies and Cypress Point were developed on the lower, tidal, section of the creek adjoining the Chickahominy River.

Waterfront homes and erosion caused by the wake of the motor boats have altered the creek's shoreline and adjoining marsh lands.

This has led to a dramatic decline in the hydrilla, both in the reservoir and in the tidal creek, but native marsh plants have not taken its place.
