in a "normal" year it will start in earnest in November. sometimes it goes early starting in October, other times no significant rain til December or even January....it depends.
i am going to construct an emergency system off of my house well as much as i hate the thought of paying PG&E for putting water in my pond. i'll run a 1/2 or 3/4 inch line to pond and make a 3 or 4 head manifold sprayer (high pressure nozzles) to both add fresh (well) water and hopefully give fish a temporoary refuge if it comes down to that.
