From The Mohave Valley News:
The Arizona Legislature on Tuesday made a formal request asking Congress to fund a study to determine the feasibility of pipelining Mississippi River floodwater to the Colorado River.
House Concurrent Memorial 2004 passed the Arizona Senate by a 23-7 vote and the Arizona House by a 54-6 margin. A memorial is not a law, but a legislative measure containing a request or proposal, asking other parties outside the Arizona Legislature’s jurisdiction to take action. HCMs have no official standing or effect, but serve as a public record of the request presented for consideration.
The memorial was introduced by Rep. Tim Dunn, R-Yuma. Rep. Leo Biasiucci, R-Lake Havasu City, is among co-sponsors.
It asks that “the United States Congress fund a technological and feasibility study of developing a diversion dam and pipeline to harvest floodwater from the Mississippi River to replenish the Colorado River and prevent flood damage along the Mississippi River.”
It also states that “If shown to be feasible, the United States Congress implement the diversion dam and pipeline as a partial solution to the water supply shortage in Lake Powell and Lake Mead and the flood damage that occurs along the Mississippi River.”
Lake Powell and Lake Mead are the two major reservoirs on the Colorado River. Both are at historically low levels and likely will trigger a Tier 1 water emergency in Arizona later this year or in 2022.
The memorial notes the low water levels of both reservoirs and the “historic flooding in 2011 and 2019 along the Mississippi River” that caused 11 deaths and more than $9.5 billion in damage.
It asks that the request be sent to the President of the U.S. Senate, the Speaker of the U.S. House of Representatives and the governors of states on the Mississippi River — Arkansas, Illinois, Iowa, Kentucky, Louisiana, Minnesota, Mississippi, Missouri, Tennessee and Wisconsin — as well as Arizona’s 11 members of Congress.
“Arizona has long been at the forefront among Western states in supporting the development and implementation of pioneering, well-reasoned water management policies,” Dunn said, a line straight out of the HCM he crafted. “Arizona and the other six Colorado Basin states are in the 20th year of severe drought and experiencing a severe water shortage. Water levels are at critical levels, jeopardizing the water delivery and power generation. A new water source could help augment Colorado River supplies.
“One promising possibility involves piping water that is harvested from Mississippi River floodwaters. Diverting this water, which is otherwise lost into the Gulf of Mexico, would also help prevent the loss of human life and billions in economic damages when such flooding occurs. This concept is already being proven in Denver, where floodwater is being successfully harvested from the Missouri River to help alleviate its water shortage.”
