Federal water engineers are heading into the final stretch for making a decision on Denver's $360 million project to divert more water from the upper Colorado River Basin.
Denver Water officials have been planning to increase water supplies for 1.3 million metro Denver residents for years.
The U.S. Army Corps of Engineers says environmental issues and paperwork have forced a delay of the decision until fall.
Last year, Denver Water and Western Slope leaders negotiated a deal to try to save the Fraser River and its trout while also letting Denver take more water across the Continental Divide.
According to the Denver Post, opponents say the project would further drain and harm the upper Colorado River.
