Nearly eight years after the Camp Fire, sediment continues to reduce storage capacity at Concow Reservoir, prompting the Thermalito Water and Sewer District to seek state funding for a major dredging project estimated to cost $50 million to $55 million. The reservoir is the primary drinking water source for about 12,200 residents in the Thermalito community. … The district is proposing to remove about 900,000 cubic yards of sediment. [Chris] Heindel [district engineer for the Thermalito Water and Sewer District] said that represents roughly 2,000 acre-feet of water storage capacity that has been displaced since the Camp Fire, though he said removing the sediment would not restore all of the reservoir’s historical capacity.
