A water diversion agreement for the Potter Valley hydroelectric project is set to see its approval by the Humboldt County Board of Supervisors Tuesday, about a week before PG&E aims to submit its plan to decommission the Scott and Cape Horn dams. This full agreement contains more details on what future water diversions from the Eel River would look like. … The basic outlines of this plan were approved by the Humboldt Supervisors in February. Tuesday’s discussion is for approval of a full agreement, before PG&E will submit its license surrender application and decommissioning plan to the Federal Energy Regulatory Commission (FERC) by July 29. Importantly for the Humboldt County Supervisors and the Eel River’s fish, the 63 page diversion agreement spells out how much water would be taken during high flow seasons — with diversion contingent on salmon and steelhead runs on the Eel.
