Wildhorse Reservoir

On the Owyhee River in extreme northern Nevada, at a higher water level than it's been in years. It was built by the Bureau of Reclamation for the Duck Valley Irrigation Project on the eponymous Paiute reservation. The Owyhee River flows north into Idaho to join the Snake River, and so (as I mentioned elsewhere) this little sliver of Nevada is actually in the Columbia River drainage. Surprisingly, and thru a convoluted set of circumstances, Owyhee is actually named after Hawaii! The left inset is a view just above the dam; the right is farther upstream, where the reservoir speads out more. This area typically has the coldest winter temperatures in Nevada, hitting -20 F or below routinely, and there's actually ice fishing on the reservoir then!
