The Ruby below the reservoir is a small, intimate, brushy tailwater that grows browns a lot better than its size suggests. It's nearly as famous for its access fights as for its fishing — the public-access question here has been argued in court, so confirm where you can legally stand before you wade in. Flows swing with irrigation demand, which means the river you fished last week may not be the one you find today.

Listed impairment causes: Temperature, Sediment, Nutrients, Habitat Alterations, Hydrologic Alteration.
