My wife and I snorkeled it around the 4th of July a few years ago near Round Valley and it was loded with pike minnow.
Some of them quite large.
"Northern pikeminnows can live at least 11 years, reaching up to 35 in (89 cm) in total length and 15 lb (6.8 kg) in weight. Female northern pikeminnow reach sexual maturity at about six years, males in three to five. A mature female can lay 30,000 eggs annually."
I have seen very large Pikeminnows on the South Fork of the American River below Chili Bar that looked to be 15#.
Maybe they can have scuba tournaments on the Eel River to spear lots of large Pikeminnows?
We used to catch them on white streamers years ago fly fishing in the Lower American River for Stripers.
