Thanks Rod,
I took a quick look via google before I posted the question and didn't really find anything on Shasta per sey, but Trinity is a no no.... I think the best course of action is to call the marina where we are renting the houseboat (been going through them for over 25 years, just missed a three years in that time) and ask them... Sold my almond ranch in central California and moved to Nevada (best move ever), just as California is running out of water for people, never mind crops...... the fish will always have water, that's the law in Cali.....
