PHOENIX (AP) -- The seven states that rely on the Colorado River are looking for ways to conserve water in a supply already stressed by population growth and an ongoing drought.
Water managers in the seven states that rely on the river -- Arizona, New Mexico, Colorado, Wyoming, Utah, Nevada and California -- believe they can create more reliable drought buffers by targeting the biggest water wasters.
Eradicating invasive plant species was among the less-traditional ideas mentioned in drought response proposals submitted by the states to Interior Secretary Gale Norton earlier this year.
At the top of the species list is the tamarisk, a non-native tree that, by some estimates robs the Colorado River of as much as 500 thousand acre-feet a year. That is nearly twice Nevada's annual river allocation.
