Well, I am pretty excited to have found this thread!!!
I live in Olivehurst, so I know Beale, YC, Marysville really really well... I know 3 places to catch tons of bass and catfish. There are a few places off Hammonton-Smartville road, and there are also 3 ponds off Feather River Blvd, as well as lots of Shad and Salmon at Star Bend boat ramp.
I only have 1 guy I go fishing with, and usually have been going about 3 nights a week.. Going to be doing a night fishing deal here pretty soon, there is a place out by Meridian which is off Highway 20 near Colusa in the Sutter By-Pass that has enormous catfish!
let me know if you want the exact locations, one of which is the California Gold Fields, near the Beale Gate there. Alright!
