"Drillings support Black Rock reservoir"

Yakima Herald Republic Online - By DAVID LESTER
"One fundamental question about the proposed Black Rock reservoir, east of Yakima, has now been answered - and it's good news for backers of the huge storage reservoir. Bureau of Reclamation officials said Thursday that bedrock on the south side of the Black Rock Valley can support a high dam. The conclusion, based on a review of core drillings, is the first definitive word from the agency about the geology of the site, east of the intersection of State Route 24 and Highway 241. Yet to be determined is how groundwater flows beneath the site and whether the reservoir will leak too much water. Also unknown is what impact extensive seepage from Black Rock would have on the Hanford Reach of the Columbia River. "
