Heavy rainfall in California's Oroville Dam has led to a record surge in the reservoir, forcing operators to open the massive spillway gates and release billions of gallons of water into the Feather River. The move is aimed at preventing potential flooding downstream.
The reservoir, which holds back California's second-largest body of water, has seen its level increase by 75 feet between December 16 and January 7, bringing it to 75% full or 136% of its historical average. This drastic rise in water levels was prompted by a series of major storms over the past three weeks.
Dam operators often let water out of reservoirs during wet winters to make room for future rainfall, allowing them to control water releases and prevent flooding downstream. In Oroville's case, releasing excess water is crucial to maintain storage space and prevent overflow.
Jeffrey Mount, a professor emeritus at UC Davis and senior fellow at the Public Policy Institute of California's water center, described the process as "a balancing act." He noted that while it's usually straightforward during wet winters, there can be high flows for days after a storm event.
The reservoir has seen an astonishing increase in its water levels, with Oroville going from 1,740,668 acre feet on December 16 to 2,578,222 acre feet today. This equates to an additional 837,554 acre feet of water, enough to fill nearly 400,000 Olympic swimming pools.
Engineers at the state Department of Water Resources opened the gates on Oroville's spillway at 6 a.m. on Monday, with releases increasing nearly tenfold from 1,856 cubic feet per second on Christmas Day to 16,135 on Monday. However, despite increased releases, the reservoir continues to rise due to incoming water flows.
Experts are hopeful that more storms in February and March will continue to boost reservoir levels and the Sierra Nevada snowpack, which provides 30% of California's water supply. The snowpack's melting snow is essential for topping up reservoirs and irrigation systems in the Central Valley.
