YAKIMA, Wash- You may have noticed some rivers around Yakima running higher than usual. It's part of a program called 'Flip-flop' put together by the Bureau of Reclamation.
At the end of the summer they let more water out of reservoirs on the Tieton and the Naches for irrigation and less out of reservoirs above the Yakima River. The Bureau says this ensures that salmon will lay their eggs in places that are always under water.
"If the water is too high and can't be sustained, then the water will drop and their nests will be high and dry and the eggs won't be viable", says Chris Lynch, and Engineer with the Bureau of Reclamation.
Lynch says the rivers will remain at these levels until the end of irrigation season. According to the Bureau, letting the water go improves the chances of filling the reservoirs next year.
