A former Interior Secretary Bruce Babbitt says the Interior Department needs to take up authority it has for contract approval on use of water by individual entities in the states of California and Arizona. The department can look at how efficiently water is being use to give approval. He suggests this approach as the states of California and Arizona are nowhere near agreement on use of water from the Colorado river. Babbitt says there is risk of deadpool where the water in Lake Mead drops to levels that make water to stop running from the lake downstream to Arizona and California.
