West Fork Eno Reservoir Expansion: Phase II
The West Fork Eno Reservoir expansion is the second phase of the town’s reservoir, which was planned in the 1990s. Construction of the first phase ― the building of the reservoir on the west fork of the Eno River in Cedar Grove ― began in 1998 and was completed in 2000. Phase II work will expand the reservoir’s volume for expected future demand by raising the normal water elevation by 10 vertical feet. The project’s planning stages began in 2013. Construction was started in April 2018. The expansion includes related clearing, road and bridge projects. The project is expected to be complete by December 2020.
The expansion includes the following elements:
- Building permanent access roads. (Underway)
- Demolishing the Phase 1 spillway of the reservoir’s dam. (Completed.)
- Installing a new spillway with notched weirs, also called piano key weirs. (Completed.)
- Clearing land from the area around the reservoir that is to be submerged. (Nearly completed.)
- Raising Efland-Cedar Grove and Carr Store roads to accommodate the higher water level. (Completed.)
- Installing a new bridge on Carr Store Road to accommodate the higher water level. (Nearing design approval.)
- Raising the reservoir’s water level about 10 feet. (Expected to begin by the end of 2020.)
