The river runs from Nevada north into Idaho and Oregon, draining about 11,000 square miles.“Generally, on the east side of the canyon, we still have good snowpack and most of the draws are still frozen,” said Flynn, general manager of the Nyssa, Ore.-based Owyhee Irrigation District. “On the west side, all the draws were running with muddy water.
