New reservoir planned in Yakima River Canyon

Posted: Updated:

YAKIMA, Wash. - A new reservoir would be built in the Yakima River Canyon as part of a plan to improve the water supply in the Yakima River Basin.

In addition to the Wymer reservoir north of Yakima, the plan calls for improve fish passage and habitat preservation in an overall agreement to make sure there's water for salmon, cities and farm irrigation.

The Roza Irrigation District and the Yakama Nation drafted the new proposal after plans were dropped for a reservoir near Moxee called Black Rock.  It would have cost as much as $7 billion.

The new plan would cost $3 to $6 billion over 30 years.  A report Monday from the Bureau of Reclamation says the benefits would outweigh the costs.
