Today we fished Shasta Lake and found a less than stellar bite, but we did find some nice rainbows. Full moon, low pressure, and changing water temps makes for a tough bite.  Another factor is the abundance of shad in the lake right now.  The trout have as much shad as they can possibly stuff in their bellies available now.  With water temps in the 65-66 degree range, the shad balls are on or near the surface and so are the trout.  When the lake glasses over, you can see trout boils all over the surface.  Today the McCloud arm in front of Holiday Harbor was loaded with shad and big trout boils.  Best bet now is to fish where the bait are found and "match the hatch" with small spoons like the Wee Dick Nite spoons that are about the same size as the shad we are seeing now.  The nights are cooling and the cloud cover will help cool the surface temps.  Once the surface temp drops below or near the low 60's, the lake will turn over and we'll have cold water available throughout the whole Shasta lake system.  Fishing will improve and we'll be in our typical fall/winter pattern.
