Is the Yuba River Basin in Peril? Fact-Checking New Bullards Bar Dam Safety
Q1: Is New Bullards Bar Dam at risk of structural failure this year?
No. Comprehensive inspections by the California Division of Safety of Dams (DSOD) and the Federal Energy Regulatory Commission (FERC) confirm the concrete arch structure is sound. The ongoing updates relate strictly to operating procedures and software guidelines, not structural emergency repairs.
Q2: Why did it take fifty years to update the Water Control Manual?
Federal water manuals historically required complex multi-year environmental reviews, inter-agency approvals, and extensive hydrology models. Advances in atmospheric river tracking over the past decade finally provided the scientific baseline required by the Army Corps to replace static 1972 guidelines with flexible, forecast-driven rules.
Q3: How does the new manual update affect water supply during droughts?
The updates actually improve water conservation. Under old rules, operators were forced to dump water if reservoir water levels were high on specific calendar dates, even when long-range forecasts showed no rain ahead. Forecast-informed protocols allow the reservoir to safely retain that water, boosting reserves for dry summers.
