The newly-renovated Oroville Dam spillway could be used as early as next week, the state Department of Water Resources said Tuesday. DWR is “closely monitoring Oroville reservoir levels and current forecasts,” the water agency said in a press release. With storms forecast in the Feather River basin, DWR said it is taking steps to prepare for use of the main spillway by the first week of April. Although the state water agency said the spillway was usable in October 2017 if needed, water has not flowed in significant amounts since the spillway crisis in February 2017, when a hole in the enormous concrete structure led to use of the emergency spillway concrete weir for the first time in history and eventually the evacuation of more than 188,000 downstream residents.
