Project Update: 7/9/2018
The Authority expects to maintain the current water level (elevation 374) for the foreseeable future, barring any unanticipated releases due to water supply needs. The Authority’s engineering consultants for the planned construction work at Round Valley have determined that the water level during construction on the three embankments should be targeted at elevation 360. The timeline for that aspect of construction is still being finalized, but drawdown of the reservoir to reach elevation 360 will likely begin in 2019.
Other aspects of the rehabilitation work at Round Valley will move forward before then. The first large planned project, abutment grouting at the North and South dams, is expected to begin later this year. Construction dates, including road closure dates for the segment of Route 629 that parallels the reservoir, will be announced here as soon as they are known.
This summer, the public may see crews digging test pits on the North and South Dams and installing instrumentation on all three embankments. This work will be done in restricted areas of the reservoir property and will not affect the public’s use of it.
