Water supply forecasts take into consideration present hydrometeorological conditions and use But generally below-normal precipitation the last several months after a very wet December.. The drop in the power forecast comes as Upper Colorado River Basin states of Colorado, New Mexico, Utah and Wyoming prepare to finalize a new drought operations plan for the giant river system. Winter Storm Warnings are in effect for elevations above 4000.Heavy accumulations of 10-20 are forecast above 6000, 3-8 to 4500 and several inches to valley floors. (Due to the angle of sunlight, this image may cause an optical illusion known as relief inversion.). Note that projections of elevation and storage for water year 2023 have significant uncertainty at this point in the season. Late last fall WAPA, which operates the electric grid and distributes the power to utilities, raised rates 30% to cover reductions in power revenue. She also sits on the Upper Colorado River Commission. average basin temperatures and precipitation for the forecast period. Lund said that throughout the reservoir's history, it has refilled to its original levels just once. Upper Colorado River Basin regularly experiences significant year to year hydrologic variability.

For five years after 2012, snow- and rainfall totals were generally low, as the region suffered through a persistent, long-term drought. 2018 brought some relief after a wet winter. But the declining water already has drained some of the fun, he said. If Glen Canyon Dam ceases to operate, we are going to have to replace that power somewhere else and it will have a bigger carbon footprint, said Bryan Hannegan, CEO of Holy Cross Energy, which buys Lake Powells hydropower to serve customers in Western Colorado. "These reservoirs are huge," Lund said. The January 2023 24-Month Study probable maximum and the February 2023 24-Month Study probable minimum inflow scenarios were used to determine the range of probable outcomes. The Glen Canyon Dam annual release has initially been set to 7.00 maf, and in April 2023 Reclamation will evaluate hydrologic conditions to determine if balancing releases may be appropriate under the conditions established in the 2007 Interim Guidelines; Balancing releases will be limited (with a minimum of 7.00 maf) to protect Lake Powell from declining below elevation 3,525 feet at the end of December 2023; Balancing releases will take into account operational neutrality of the 0.480 maf that was retained in Lake Powell under the. CNN's Bill Weir has more. While the lake was significantly higher in 2011 and 2012 than in 2005, a careful comparison of the side canyons reveals that the level was still not back to 1999 levels, when the lake was near full capacity. google_ad_type = "text_image"; n$L{Z.

Despite those releases, Powell dropped below 3,525 last month, hitting 3,523, another historic drought landmark. We need to get ourselves prepared," he says. At the same time, electric utilities across the West are looking for other green options and hoping that hydropower production wont stop altogether.

The end of January elevation and storage of Lake Powell were 3,523.45 feet (177 feet from full pool) and 5.45 million acre-feet (maf) (23 percent of live capacity), respectively. Click for Details, Current Snowpack Conditions for Upper Colorado Basin. However, these responses can have a noticeable impact on the river downstream of Glen Canyon Dam. Consistent with Section 6.D.1 of the Interim Guidelines, Lake Powells operations in water year 2023 are governed by the Lower Elevation Balancing Tier (LEBT) with an initial projected water year release volume of 7.00 maf.

Because the 2022 operations were designed to protect critical elevations at Lake Powell, Reclamation will implement Lower Elevation Balancing Tier operations in a way that continues to protect these critical elevations, or preserves the benefits of the 2022 operations to protect Lake Powell, in water year 2023. Prepared by Ashley Nielson NOAA, National Weather Service Colorado Basin River Forecast Center Salt Lake City, Utah www.cbrfc.noaa.gov Contents Last July, to protect the 3,525 buffer zone, Reclamation ordered emergency water releases from three reservoirs in the Upper Colorado River Basin.

In addition to the February 2023 24-Month Study based on the Most Probable inflow scenario, and in accordance with the Drought Response Operational Agreement (DROA)), Reclamation has conducted model runs in February to determine a possible range of reservoir elevations. The release volume from Glen Canyon Dam in January was 500 kaf. The Water Desks mission isto increase the volume, depth and power of journalismconnected to Western water issues.
