Drought monitor

Drought conditions worsened notably in Washington, Oregon, Montana and northern California over the last three months. Hot and dry conditions dominated the West in July and early August, leading to the expansion of multiple drought categories ranging from D0 to D4 (see maps below) and numerous large fires. Wildfire potential for the remainder of August is above normal. For the latest on weather, please see AgWest’s Weekly Weather Updates with Eric Snodgrass.

Year-to-date precipitation

Year-to-date precipitation levels are close to their historical averages across the West, with notable exceptions in Washington, northern Idaho, western Montana, north San Joaquin Valley in California and northwest Arizona.

Reservoirs with low water levels

While reservoir levels across California are strong, Arizona, Oregon and the Yakima River Basin in Washington face challenging conditions.

Reservoirs with water levels below 80% of their historical average

Data as of August 8, 2024.

Description – Reservoirs are an important source of water for agricultural producers throughout the West. This section identifies those with water levels at 80% or below of their historical average for the given period. Reservoirs at or above 80% of their historical average water levels are not included in this list.

Updates impacting water access

Arizona

In a new proposal to the federal government, Arizona, California and Nevada collectively agreed to cut their water use when the Colorado River watershed levels dip below certain thresholds. Estimates suggest Arizona would have to cut water use by an average of 27% each year.

California

The Department of Water Resources (DWR) increased the State Water Project (SWP) allocation from 15% in February 2024 to 40% in April 2024, reflecting favorable water supply and snowpack conditions. Gains were experienced across each region. Attachment A of the Notice to State Water Project Contractors shows allocation by district.

Bureau of Reclamation increased the Central Valley Project (CVP) water allocation for south-of-Delta agricultural contractors from 40% to 50% of their contracted supply. North-of-Delta contractors remain at 100% of their contracted supply.

California’s DWR finalized its first public facing Long-term Drought Plan for California. Proposed actions include modernizing SWP infrastructure in the Delta, identifying and investigating water storage opportunities throughout the state, further planning for drought salinity barriers on the West Fals River, advancement of DWR’s Forecast-Informed Reservoir Operations and seasonal forecasting, and investing in habitat creation, restoration of tidal wetlands, floodplains and rearing habitat for juvenile salmonids.

Idaho

A temporary agreement was reached between the Idaho Department of Water Resources (DWR) and several groundwater districts to avoid curtailments in the Eastern Snake Plain Aquifer. While this represents a win in that producers will continue to access water this season, negotiations will need to resume to arrive at a long-term solution. Estimates vary, but curtailments could impact 330-500 thousand acres of farmland in eastern and southern Idaho.

Montana

Due to a siphon(s) blowout near the head of the Milk River at St. Mary in northern Montana, it is reported that the irrigation districts along the Milk River may have severely depleted irrigation water availability until the new siphon system is completed. The project is slated for completion until August 2025.  This will greatly affect producers along the Milk River in north central Montana.

Minimal snowpack this winter has limited irrigated water availability along the eastern front of the Rocky Mountains. The Greenfields Irrigation District (GID) in north central Montana was allocated 1 acre-foot of water, when they normally get 2 acre-feet. Reports suggest that as of August 4, 2024, many of the flood-irrigators in the GID ran out of water two weeks ago, and pivot irrigators may be soon to follow. Pondera County Canal and Reservoir Company (PCCRC) in north central Montana was allocated 4 inches of irrigation water, when they are normally allocated 1 acre-foot.  Operators ran out of water very early in the PCCRC. Several irrigation projects/districts in western/northwestern Montana face similar water limitations.

Oregon

There are some specific areas around Burns, Redmond and Klamath Falls experiencing irrigation water concerns due to historic drought/water table issues and/or environment concerns.

Washington

Junior water rights users of the Yakima River will have their access to water cut back to 51% of their normal allocation due to low precipitation and storage in the Yakima Basin Reservoirs.

Drought across Washington is expected to expand due to low snowpack and precipitation levels. On April 16, 2024, the Washington State Department of Ecology issued an emergency drought declaration for the entire state, which may open up tools such as public funding to mitigate the impact of lost crops. Impacted commodities may include hay, wheat and tree fruit.
