This 1,110-acre water supply reservoir for the City of Newport News is situated along the New Kent and James City County line. The reservoir provides a scenic destination for anglers to try their luck on a variety of fish species. The fishery has abundant populations of largemouth bass, bluegill, chain pickerel and black crappie. Carp, bowfin, and longnose gar provide alternative quarry. Gizzard shad and blueback herring are the main forage species. The public boat ramp allows anglers to launch their boats near the center of the reservoir. The numerous creek arms and coves provide anglers a chance to explore and hopefully find their next great fishing spot.
Newport News Waterworks is in the process of conducting repairs to the dam's spillway on Diascund Reservoir. The water level has been drawn down several feet to allow for the necessary repair work to be completed. Anglers should be cautious when operating boats on the reservoir due to the various shallow sand bars and stump fields that are present.
