Mismanaged Water in the West

The California Drought is part of the greater Water Crisis in the Western United States (WUS), affecting not only California but also Arizona, Nevada, and other states. The causes of the crisis are both anthropogenic and natural, however, since water resources management should be done in a way that takes into account hydrological cycles and overall water fluxes, it could be said that this is an entirely anthropogenic disaster. A brief history of the WUS shows clearly the need for Integrated Water Resources Management (IWRM) in changing ‘water rights’ in the US.

A recent project by ProPublica, “Killing the Colorado”, outlines different aspects of the crisis, ranging poor regulatory understanding of hydrology with a relentless agricultural and population growth to generally unsustainable management (Lustgarten, 2015a). A major source of water is the Colorado River Basin, which has a fluctuating amount of water capacity, with approximately 18 MAF of flow being measured during the 1922 Colorado River Compact, but flows ranging from 3.8 MAF in 2002 to 22.2 MAF in 1984. with one of the first major interstate management efforts being the 1922 Colorado River Compact. The 1922 Compact apportioned 15 MAF throughout the Upper and Lower Colorado River Basin, and 1.5 MAF were allocated to Mexico, so there’s 16.5 MAF allocated, but natural average flows could be about 13 MAF (Gelt, 1997).

The exact specifics of how much the water is changing aren’t very important, and will probably change with more accurate modelling and in-situ and satellite data availability, but the results still stand: The amount of water is in flux, and continuing growth will result in massive shortages during years of lower flows. Of course, the Colorado River isn’t the only source of water in California. Large amounts of groundwater are also being depleted, in fact to the point that parts of California are subsiding at an average of a foot per year, with parts of San Joaquin Valley going at 2 inches a month (2 feet per year). The USGS estimated about 12.3 Billion GPD of groundwater removal in California (population 37 million), roughly 12 times the amount of water NYC daily consumption (population 8 million), or nearly 20% of all groundwater pumped in the United States (Bell, 2016).

Outside of the unsustainable amount of water being used, the people managing it aren’t acknowledging the science. Scientists have identified that surface and ground waters are connected, and as the ProPublica piece “Less Than Zero” shows, California isn’t acknowledging that (Lustgarten, 2015b). In fact, a recent piece of California legislation mandated that regulators were not allowing to mention the connection between groundwater flows and surface water until 2025. This is meant to give them more time to prepare better regulatory measures, but it’s a common symptom of management without science.

A remedy to this has been proposed, but it does not appear to have been used in this management policies of the West. Integrated Water Resources Management (IWRM), espoused by UNESCO and hydrologists, is a process which promotes the coordinated development of and management of water, land, and related resources, in order to maximize the resultant economic and social welfare in an equitable manner without comprising the sustainability of vital ecosystems. (Loucks et. al 2005) The IWRM is a system that could be used to fix the WUS, but only through the push by scientists to have their science be a part of policy.

By considering the links between surface and groundwaters, by using drought (availability) models that are able to reasonably discern seasonal and yearly fluctuations in availability, and by making sure that these predictions form the backbone of allowances, a system will be developed that allows growth to occur without collapsing unto itself. Edward Abbey said that, “growth for the sake of growth is the ideology of a cancer cell,” an ideology that should be considered when developing massive urban and agricultural developments in an arid climate.

I have not gone into the different water users and how efficiency may be improved, but the biggest portion of water savings can come from better agricultural practices. The hydrological climate in the WUS isn’t great for growing crops, and this needs to be considered – more efficient irrigation has to be used, and the federal government needs to consider removing subsidies for crops that really shouldn’t be grown in the WUS.

One major lesson of the California Drought and the Water Crisis is the same that the former Secretary of the Interior, Stewart Udall, pushed for in his tenure: Let science guide the way we develop our resources, but have a staunch conservatism in development. Do not let development go unchecked, and don’t let managers who have no knowledge of water systems make the final decision on how water is managed.
