Workers could be seen Friday walking and driving along the mostly dry main spillway of the Oroville Dam conducting concrete work. The California Department of Water Resources, which oversees the dam as well as Lake Oroville, announced Friday that the work consists of joint sealant repair work as well as laying concrete. While this work has been ongoing, the timeframe of the project has been extended until Dec. 1. According to the update by DWR, the spillway has been up to par throughout 2023 with considerable outflows as a response to heavy storms and the highest lake level in years, reaching capacity in spring. In total, the spillway passed 2.37 million acre-feet of water which is 67% of Lake Oroville’s capacity.
