The system for irrigating is vastly different between Wyoming and Imperial Valley, and because of this, water negotiators of the region have vastly different points of view. In the Green River Basin, there are 2500 gates diverting water onto ranchers’ lands, but in the greater scheme of things, the basin is essentially a collector system. Some of those far-flung gates are “unregulated,” or unmonitored. The Green River has 2,000 named natural tributaries. Accurately measuring the supply and consumption of water in such a system is a work in progress.

In the Imperial Valley, we have one gate diverting water from the Colorado River. It is where Imperial Dam turns water into the All-American Canal. While the Green River Basin is a collector system like the roots of a tree, ours is a distribution system like the branches to the leaves. The IID has 5500 gates. Since every one of them is monitored by the IID, water supply and consumption are easy to measure with gauges throughout the system. 

Water management is a world apart as well. In the Green River Basin, there are thirty-seven small water distribution agencies, both public and privately owned, often with zero or a handful of fulltime employees. There are irrigation districts, conservancy districts, ditch companies, and canal companies. Ranchers, and often non-agricultural property owners, pay an assessment, or a flat fee, or a per-acre fee, or a price per share for water delivery. The water itself is owned by the state of Wyoming and is made available for free. The overseer of all this is the Wyoming State Engineer, which in turn has a representative on the Upper Colorado River Commission, the governing agencies for the Upper Basin states. 

In the Imperial Valley, the Imperial Irrigation District is the sole holder of water rights to Colorado River water and the sole manager for water distribution. Here, as in all the Lower Basin States, the Bureau of Reclamation is our overseer. With nearly 500 employees in its water division, IID outguns the whole state of Wyoming for water workers about 2 to 1. The Bureau also supplies IID’s 3.1 million acre-feet of water for free, and IID charges farmers $20 an acre-foot (af), a fee subsidized by revenue from the transfer of water to the San Diego County Water Authority. Industrial water users pay a much higher fee…

So far, the cuts that Mother Nature has forced on Wyoming and others in the Upper Basin states, and the cuts agreed to by Arizona, Nevada, and California, are far below the amount necessary to save the reservoirs from circling the drain in the next few years. Negotiators have until the end of this month to reach consensus on a plan to satisfy the Bureau of Reclamation’s demand for 2-4 million acre-feet of cuts in water use next year. We’re all unhappy in our own way on the Colorado River. Like the sparsely populated Cowboy state, we can only fight the good fight against the odds.

  1. When will the Lower Colorado River Compact states finally get serious about conservation and stop overdevelopment with dwindling water supplies??

    1. The lower basin cities have embraced conservation: https://coyotegulch.blog/2023/01/12/decoupling-consumption-from-population-on-the-colorado-river-southwestern-cities-shrink-their-water-footprint-even-as-they-grow-land_desk/.

      The problem is keeping conserved Ag water from fueling development or increasing acreage under cultivation. Diversions are a property right under current law and it is very difficult to lay down rules about how a property owner can use their property right without crossing the line to a “taking”.

      Thanks for commenting.
