On July 25, 2016, the City of Raleigh received approval from North Carolina Division of Energy, Mineral, and Land Resources to impound Northshore Lake.

The project calls for substantial improvements to the lake's dam and spillway. The new spillway will be a drop-chute type structure. The normal pool elevation of the lake will be lowered approximately 1.3 feet from its current elevation. Portions of the lakebed will be dredged. A sediment pool near the headwaters of the lake will be constructed to pool suspended sediment from upstream. The new normal pool water-surface elevation will be 262.5 feet.

The goal of this project is to meet NC Dam Safety requirements for public safety, improve water quality, and to reduce downstream flooding hazards.

Northshore Lake is classified as a small, high-hazard dam with North Carolina Dam Safety. Northshore Lake has a history of overtopping the dam and New Hope Church Road downstream causing flooding. A floodplain study was completed of the New Hope Tributary in order to determine the extent of flooding that takes place along the tributary. In addition, the City of Raleigh organized and prioritized all the lakes within the City and ranked them for preservation under the City's Lake Preservation Policy. Northshore Lake was identified as a top ranking lake on the preservation list. The lake is being redesigned to reduce downstream flooding, protect water quality, and also meet North Carolina Dam Safety requirements.
