Road closures Planned for County Route 629
Abutment Grouting and Road Closure Notification
Grouting of the abutments at the South Dam has been ongoing for the past few months. Work will shift to the North Dam this fall. In connection with work at the North Dam, the segment of County Route 629 that parallels the Reservoir between Old Mountain Road and the Boat Launching area is scheduled to be closed from sometime in October to mid to late December, 2019. Access to the Boat Launching area will remain open. Detour signage will be placed at both ends of the road closure. Any changes to these dates will be announced here.
Reservoir Drawdown Has Begun
In anticipation of the next phase of the Round Valley Project, the rehabilitation of its three earthen dams, the Authority has begun drawing down the Reservoir water level. The dam rehabilitation phase is the largest and final phase of work and site preparation is anticipated to begin in the late winter/early spring of 2020. The target maximum water elevation level for construction is 360’ and as of September 16, 2019, the level is 369.9 (full pool is 385’). The Authority plans to lower the pool at a rate of approximately 1 – 1.75 feet of elevation per week until the target level of 360’ is met. The pool will remain at or below this lowered level for the duration of the project, which is currently scheduled to be completed in late 2021. If drought occurs during construction and additional releases are necessary for water supply, the pool would naturally be reduced further. Additional details about this phase of the Round Valley Project, including water levels and a second closure of County Route 629 will be announced here as they are established.
