As of Oct. 26:
- West Fork Eno Reservoir is 71 percent full.
- Lake Orange is 100 percent full.
- There are 213 days of water supply remaining, based on recent demand and no further rainfall.
- Current risk of drought shortage is minimal.
- Average water use for the week was 1.72 million gallons per day.
- Average water use for the last four weeks was 1.72 million gallons per day.
- Compared to the same four weeks last year, the town used 0.29 percent more water.
Hillsborough water customers are not subject now to any water use restrictions. The town is subject to Stage 1 water withdrawal restrictions, limiting withdrawal from the Eno River to 1.51 million gallons per day. Since the town is using less than that amount and releasing extra water from the West Fork Eno Reservoir, this limit does not have any effect on operations. Lake Orange is currently full and spilling
Construction on the Phase 2 expansion of the West Fork Eno Reservoir began in April 2018. The water level will remain at least 4 feet below full to enable work on the dam and spillway and will remain lowered while construction proceeds. Completion is expected in August 2019. Fall hydrant flushing took place during the entire month of October, which accounts for part of the increase in usage.
