Unclear if anything would go extinct but most of that water drains into Humboldt Bay. There are several robust salmon and trout fisheries which would almost certainly take a beating. These steams support river otters whose numbers have never really recovered from Russian and American fur trappers and those streams support an enormous number of migratory and local bird, fish and amphibian species. Unclear what might go extinct and what would merely take a beating but it is pretty clear from similar projects in the PNW that the ecological consequences would be significant. A visit to Humboldt might change your thoughts on the topic. It is one of the most beautiful places on Earth. Not only does it boast the tallest trees on the planet but it is one of the few places in America that I would describe as wild and free. The scars of clear cutting from the 60s are still visible but the land is still alive in a way that it just isn’t in a lot of the State. Characterizing the issue as one between two extremes is a straw man. The rivers of Northern California are already heavily engineered. The current levels were established after the environmental consequences of that engineering was deemed unsuitable for the communities in the region. The Central Valley has effectively engineered its rivers out of existence and it is still not enough. It will never be enough. There is only one extreme in question here.
