Restoration Efforts for Salmon Habitat in the Tuolumne River

Environmental groups and irrigation districts are working to bring more salmon back in the Tuolumne River near Modesto.

Now people are trying to help them recover by rebuilding their habitat, but environmentalists argue that what’s really needed is just more water.
