Repairs planned for Diascund Reservoir

Spillway repairs are planned at Diascund Reservoir at the border of James City and New Kent County, beginning in the late spring or early summer of 2014.

During a routine inspection of the dam and spillway, Newport News Waterworks staff observed a problem with the concrete slabs that carry the water downstream when the main spillway overflows. In order to inspect the area, Waterworks intentionally lowered the level of the reservoir and it will remain lowered for about two years to ensure the continued stability and safety of the dam. A second issue arose following Tropical Storm Andrea in June, which required the company to lower the reservoir level even further.

Maintenance work is underway near the reservoir pumping station’s intake. The fish population and the sterile grass carp should not be impacted.

During the span of time during repair operations, some boating access will be temporarily limited. Following the completion of the work, the water level will be returned to the previous level of about 18 inches below full capacity (weather permitting).

The reservoir is maintained by Newport News Waterworks as part of its source water system. A state-owned public boat ramp is located at the reservoir.

“While this has some impact on recreation activities in the reservoir, the lower lake levels will encourage the growth of plants within the protective buffer surrounding the reservoir,” said Waterworks watershed property administrator Andrew Rich in a press release. “Diascund remains a beautiful part of the rural landscape and an important water source for the Lower Peninsula.”

Repair costs are currently unknown. Repairs are expected to last between nine to twelve months.
