This week in… Groundwater

Last Tuesday, Sacramento Superior Court Judge Allen Sumner ordered Siskiyou County to regulate groundwater pumping in order to protect the Scott River. The Environmental Law Foundation, the Pacific Coast Federation of Fishermen’s Associations, and the Institute for Fisheries Resources brought the case against the county and the State Water Resources Control Board after groundwater pumping had caused water levels in the Scotts River to decline dramatically, in some cases to the point where the river would dry up in the summer and fall, impacting fish and, notably, navigability.

Under California law, the state holds navigable waterways “in trust” for the benefit of all Californians and must take this responsibility into account when making decisions that will impact the public trust. The court decision states that, “the court concludes the public trust doctrine protects navigable waterways from harm caused by groundwater extraction…[and]  the County, as a subdivision of the State, is required to consider the public trust when it issues well drilling permits.” 

In response to the decision, State Board attorney Michael Lauffer told Bloomberg BNA, “Judge Sumner’s decision is an important and thoughtful decision which reaffirms that the public trust doctrine protects our state’s navigable waterways.”

The county is expected to appeal the decision.
