NOTE:  This series will be updated through the preparation of the 2026 Annual Operating Plan (AOP).

  • We present recent and relevant news features about the very serious issues that face the Colorado River Basin.
  • We present baseline policy documents, climate science, social science and solutions.
  • The problem is human-caused: 1) over-consumption of surface water and aquifers; 2) water conservation programs are actually water transfer programs and will not reduce consumption and will harden the embedded demand; 3) the reservoir system can only manage little droughts and little floods; 4) misquided planning and zoning (not resilient and not sustainable); 5) climate disruption: altered circulation patterns in ocean and atmosphere in response to greenhouse gas loading from burning fossil fuels at rates greater than the planet's ability to absorb carbon into the ecosystems of ocean and land.
  • The solution is: work with nature's geography and climate; restoring balance is the key objective.
  • We recommend that the nonsense stop immediately and get this house in order.


2021, September 22: FIVE-YEAR PROJECTIONS
Note: USBR projections, since 2007, have consistenty fallen between the 50th percentile and the 10th percentile. If this pattern remains consistent through the next decade, then all the reservoirs will indeed vacate; the consequence of mega-drought.
Note: On The Colorado (OTC) understands that projections into the 90th percentile are possible, because global climate disruption includes anticipating swings in long-term hydryology; a swing that could include mega-flood events. For example, in the summer of 2021 there have been devastating floods in China, Germany and Turkey. Wikipedia.


2008, February 12: WHEN WILL LAKE MEAD GO DRY?

"Pierce said the conclusions in the Scripps study are based partially on an estimated reduction in runoff of 20 percent over the next 50 years. He said that figure was used because it split the difference between the 10 to 30 percent decrease in runoff the Intergovernmental Panel on Climate Change predicts will occur over the next 50 years." Associated Press.
Note: Under the operating criteria of 2007 Interim Guidelines, when a shortage tier elevation arrives at Lake Mead, it also means that the capacity at Lake Powell is significantly diminished. The management of the two reservoirs is similar to a transportation vehicle that operates with two fuel tanks.
