River Flow Advisory Bureau . of Reclamation Upper Colorado Region Salt Lake City, Utah Vol. 15, No.I March 1985 The water supply outlook for the Upper Colorado River Basin this spring is good, with most tributary flows being slightly high for this time of year. The March 1 forecasts indicate 130 percent of normal inflow to Lake Powell. Colorado River at Westwater Canyon The flow of the Colorado River is 6, 000 cfs, which is 200 percent of normal for the first part of March. The snowmelt runoff forecast is for 144 percent of normal. Cataract Canyon Including the Green River The flow through Cataract Canyon is 12,000 cfs -- 185 percent or normal -- with the snowmelt runoff forecast at 125 percent of normal. Lake Powell Lake Powell is at elevation 3,675 feet. It is expected to reach elevation 3,698 feet -- 2 feet below full -- by next July. Colorado River Through Grand Canyon Releases out of Glen Canyon Dam from March through June are expected to be above normal -- averaging 16, 000 cfs with some fluctuations. The minimum release for short periods of time each day will probably be greater than 3, 000 cfs. This is the first time since May 1983 that power releases have fluctuated during the day. Upper Green River - Fontenelle Reservoir The elevation of Fontenelle Reservoir is 6, 480 feet. The present release of 700 cfs will be increased as the inflow, which is expected to be about 86 percent of nor~al, increases. Page 2 Green River Flows Below Flaming Gorge Dam Flaming Gorge Reservoir is now at elevation 6,021 feet and is expected to increase to 6,035 feet by this summer. This is 5 feet short of full . Releases from the dam, fluctuating each day and week, are expected to be about normal this spring and summer. Green River at Green River, Utah Green River flows are at 6,000 cfs, or about 170 percent of normal. The spring runoff is forecast at 105 percent of normal. San Juan River below Navajo Dam The current release from Navajo Dam of 2,500 cfs will be maintained for several weeks. The flow of the San Juan River at Bluff is 3,000 cfs. Navajo Reservoir is now at elevation 6,061 and is expected to increase to 6,083 by this summer . The runoff forecast is 136 percent of normal. Dolores River - McPhee Reservoir The March 1 forecast of runoff for the Dolores River is 131 percent of normal. The current release from McPhee Dam is 1,000 cfs, which will increase or decrease according to inflow and the filling criteria. Gunnison River - Blue Mesa Reservoir The elevation of Blue Mesa Reservoir is now 7,465 feet and is expected to reach 7,516 by this summer, which is 3 feet short of full.

Colorado River Slideshow Title TK
The Colorado River: Lifeline of the Southwest { The Headwaters The Colorado River begins in the Rocky Mountains at elevation 10,000 feet, about 60 miles northwest of Denver in Colorado. The Path Snow melts into water, flows into the river and moves downstream. In Utah, the river meets primary tributaries, the Green River and the San Juan River, before flowing into Lake Powell and beyond. Source: Bureau of Reclamation The Path In total, the Colorado River cuts through 1,450 miles of mountains, plains and deserts to Mexico and the Gulf of California. Source: George Eastman House It was almost 1,500 years ago when humans first tapped the river. Since then, the water has been claimed, reclaimed, divided and subdivided many times. The river is the life source for seven states – Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming – as well as the Republic of Mexico. River Water Uses There are many demands for Colorado River water: • Agriculture and Livestock • Municipal and Industrial • Recreation • Fish/Wildlife and Habitat • Hydroelectricity • Tribes • Mexico Source: USGS Agriculture The Colorado River provides irrigation water to about 3.5 million acres of farmland – about 80 percent of its flows. Municipal Phoenix Denver About 15 percent of Colorado River flows provide drinking and household water to more than 30 million people. These cities include: Las Vegas and Phoenix, and cities outside the Basin – Denver, Albuquerque, Salt Lake City, Los Angeles, San Diego and Tijuana, Mexico. Recreation Source: Utah Office of Tourism Source: Emma Williams Recreation includes fishing, boating, waterskiing, camping and whitewater rafting in 22 National Wildlife Refuges, National Parks and National Recreation Areas along river.

Before Blue Mesa
The Uncompahgre Journal February, 2014 CHIPETA CHAPTER • COLORADO ARCHAEOLOGICAL SOCIETY Volume 31, Issue 2 Before Blue Mesa - by Lautie Labak No matter how often you travel Colorado Highway 50 between Gunnison and Montrose, the view takes your breath away as you round a curve and see the shimmering waters of Blue Mesa. Midway along the reservoir, you pass the spires of the Dillon Pinnacles. The pinnacles have stood for eons, but Blue Mesa reservoir was formed only fifty years ago. David Primus of Gunnison has researched archives and interviewed local families to learn about the area history from the 1880s to the 1960s. David Primus’s presentation at a recent Chipeta Chapter meeting in Montrose explored the history of the Gunnison River Valley before Blue Mesa Reservoir. Some of the audience members at Primus’s presentation had lived in the valley or worked construction jobs on the dams, highways and bridges. For each of them, the Blue Mesa story is a part of their own personal history. Today Blue Mesa is the largest body of water in Colorado. From 1965 to 1970 the waters slowly rose to cover the canyons and meadows of the Gunnison River val- ley. Along the rail line, water covered the little supply towns of Iola, Hendersonville, Cibolla, and Sapinero. Water covered the cattle ranches, trout fishing resorts, railroad tracks, roads and bridges. Water covered the archaeological remains of 12,000 years of prehistoric occupation by Native Americans. Before the reservoir filled, archaeologist Robert Lister conducted a survey of the valley, locating numerous prehistoric campsites. Many of presenter David Primus’s historic photographs feature a Denver & Rio Grand train belching black smoke as it chugs and sways The Uncompahgre Journal Published 8 times annually by the Chipeta Chapter of the Colorado Archaeological Society.

Lake Powell Elevation Projections
September 2021 24-Month Study Projections Lake Powell and Lake Mead: End of Month Elevation Charts Explanation of Hydrologic Scenarios In addition to the September 2021 24-Month Study based on the Most Probable inflow scenario, and in accordance with the Upper Basin Drought Response Operations Agreement (DROA), Reclamation has conducted model runs in September to determine a possible range of reservoir elevations under Probable Minimum and Probable Maximum inflow scenarios. Normally, outside of DROA, Probable Minimum and Probable Maximum model runs are conducted in January, April, August, and October. The Probable Minimum inflow scenario reflects a dry hydrologic condition which statistically would be exceeded 90% of the time. The Most Probable inflow scenario reflects a median hydrologic condition which statistically would be exceeded 50% of the time. The Probable Maximum inflow scenario reflects a wet hydrologic condition which statistically would be exceeded 10% of the time. There is approximately an 80% probability that a future elevation will fall inside the range of the minimum and maximum inflow scenarios. Additionally, there are possible inflow scenarios that would results in reservoir elevations falling outside the ranges indicated in these reports. Consistent with the Upper Basin DROA provisions to protect a target elevation at Lake Powell of 3,525 feet, this September 2021 24-Month Study includes releases from the upstream initial units of the Colorado River Storage Project Act to deliver an additional 181 thousand acre-feet
