EPA May Block Planned Dam Near Denver

WASHINGTON —  The Environmental Protection Agency raised serious concerns Friday about a controversial proposed dam and reservoir in Colorado, threatening to scuttle the $500-million project if no additional safeguards are provided.

EPA Administrator William K. Reilly said the Two Forks Dam project near Denver “could result in very serious adverse environmental impact” and ordered the regional office to immediately examine “alternative water sources” with city officials.

Reilly announced he had begun procedures which amount to overruling a construction permit issued earlier this month by the Corps of Engineers and which could lead to a veto of the project if compromises are not worked out.

Environmental concerns have centered on the fact that the 615-foot dam and reservoir would flood a vast area where the South Platte and its North Fork meet about 25 miles southwest of Denver. It would put under 500 feet of water a 20-mile area, including the scenic Cheesman Canyon, which has some of the best trout fishing in the state and is home for a variety of wildlife.
