When I retired we lived at our cabin in Soda Springs at Serene Lakes full time for several years. Lake Spaulding was only a few miles away down Hwy.20 and we fished it several times throughout the year but never really had a "good" day. The headwaters of the Yuba feeds Spaulding and fishing was always good both above and below the lake, but the lake never really did much for me.
In the immediate area there were so many other lakes that produced well, we just never seemed to go to Spaulding much.
