Todd,

SCL ran higher than normal flows because there was an above average water supply. There was enough water to keep redds covered through fry emergence. Had they not run higher flows in March and April, spawning flows in May (the peak period) would have been even higher, resulting in significant redd dewatering prior to emergence. If you or Joe want the documentation on what SCL did, and why, and the results, I'll connect you to it.
