With Delta smelt numbers at all-time lows, state officials on Tuesday released a list of more than a dozen projects they’re hoping to undertake in the next few years in a last-ditch effort to stave off the fish’s extinction.

One of those plans is sure to be contentious. The “Delta Smelt Resiliency Strategy” released Tuesday by the California Natural Resources Agency calls for allowing between 85,000 and 200,000 acre-feet of extra water to wash out to sea this summer to bolster smelt habitat.
