For those who are not aware, PG & E is in the process of terminating its permit to operate the Van Aarsdale tunnel which diverts water from the Eel River near Potter Valley.
Should the tunnel be shut down, then there will be no water flows into the east fork of the Russian River into Lake Mendocino from the Eel River.
As a result, there is a good likelihood of the Russian River drying up with the exception of deep pools north of Healdsburg.
The impact to agriculture in Mendocino and Sonoma counties should this happen will be significant with further impact to the economies of both counties.
For those that are concerned, contact with your county supervisor is recommended.
