BOISE, Id.- A major setback in the effort to build the Black Rock Reservoir.
The U.S. Bureau of Reclamation is being very cautious when it comes to the reservoir's future, but they do admit it's not positive news.
The new report states that seepage from the proposed reservoir would travel toward the Hanford nuclear site and raise the water table underneath enough to move previously immobile chemical sediment toward the Columbia River.
"It certainly is sobering news. It's not unexpected, anytime you would construct a reservoir off-site, you would expect to see some seeping from that, what happens in this case is it does seem to be traveling towards some, a site where there are buried contaminants," said Diana Cross with BOR.
Cross says the Bureau considering other options for storing water for the Yakima Valley.
The goal of the reservoir is to better serve irrigation needs in the area and assist fish spawning on the Yakima River.
