US Army Corps of Engineers
The Phase II Dams and Spillways contractor (Flatiron/Dragados/Sukut Joint Venture, or FDS JV) continues construction activities. As a result, the site including Engineers Point is an active construction area and is off limits to the public.
Corps policy prohibits public operation of unmanned aircraft systems, such as drones, on or above federal lands and waters managed by USACE. The policy is intended to ensure critical infrastructure security and public safety.
Looking Ahead (Next 30+ Days)
Construction on SR155 near the Main Dam will continue through 2019. The contractor is currently constructing the embankment for SR155 detour. Traffic is expected to be moved to the detour in fall 2019, which will create periodic traffic delays. USACE will provide updates on expected impacts via public outreach, the monthly SITREP, and the Isabella Task Force.
Production blasting will continue through all of 2019 and into 2020. The contractor will establish a safety perimeter to restrict access during each blast, including along SR155 near the Main Dam, which will be temporarily closed during blasting operations.
Work on the Old Isabella, South Fork, and Auxiliary Dam recreation areas is expected to resume this month. The recreation areas will remain open, however, the contractor will mark certain areas with those sites off-limits to ensure public safety during construction operations.
Current Lake Status (as of September 3, 2019)
The current pool resides at 242,376 acre-feet, which is 67 percent of restricted pool, and elevation of 2,571.2 feet.
