"With Lake Mead dropping to levels that could trigger water cutbacks in less than two years, there's been a lot of talk lately about negotiating a deal to keep the reservoir from falling even further.
But in a new report, scientists say the situation is just as worrisome upstream at Lake Powell.
The declines there during the past 18 years, they say, also reflect the Colorado River's worsening "structural deficit."
The 10 scientists, who make up the Colorado River Research Group, said even though the four Upper Basin states — Colorado, New Mexico, Utah and Wyoming — haven't been using all the water they're legally entitled to, Lake Powell has declined due to extra water releases into Mead."
