How to Prepare for Traveling on I-70 in Glenwood Canyon (Spring 2021)
How to prepare for traveling on I-70 in Glenwood Canyon (Spring 2021) I-70 in Glenwood Canyon Motorists traveling on Interstate 70 should prepare for reduced speeds, slick roads and limited visibility in Glenwood Canyon, as well as other spring weather conditions that are common along the I-70 mountain corridor. If there is rain in the forecast, motorists should anticipate a possible safety closure of I-70, rest areas and the Glenwood Canyon bike path in the canyon. These safety closures are to protect the traveling public from the potential for debris flow, mudslides or rockfall. Construction impacts will be much lighter on I-70 in Glenwood Canyon compared to Summer 2020. To ensure safety, motorists should plan for occasional lane closures, obey reduced speeds and drive with caution. CDOT also urges travelers to stay focused on the road and avoid distracted driving. Please see below for information about the Glenwood Canyon rest areas and bike path. How to plan ahead Motorists planning to travel on I-70, visit rest areas or ride the bike path in Glenwood Canyon should pay close attention to weather forecasts. I f there is rain in the forecast, be prepared for a safety closure of I-70, rest areas and bike path. CDOT recommends that travelers have a back up plan in the event that closures are necessary. Please refer to w ww.cotrip.org for the latest road conditions and route options. More information is below for planning an alternate route. CDOT also recommends that travelers bring an emergency kit with water, snacks, a flashlight and a blanket, as mountain conditions often change suddenly. -

The Colorado River Aqueduct
Fact Sheet: Our Water Lifeline__ The Colorado River Aqueduct.

It was originally conceived by creation of a medical system for contract workers that would William Mulholland and designed by Metropolitan’s first Chief become the forerunner for the prepaid healthcare plan offered Engineer Frank Weymouth after consideration of more than by Kaiser Permanente. 50 routes. The 242-mile CRA carries water from Lake Havasu to the system’s terminal reservoir at Lake Mathews in Riverside. This reservoir’s location was selected because it is situated at the upper end of Metropolitan’s service area and its elevation of nearly 1,400 feet allows water to flow by gravity to the majority of our service area The CRA was the largest public works project built in Southern California during the Great Depression. Overwhelming voter approval in 1929 for a $220 million bond – equivalent to a $3.75 billion investment today – brought jobs to 35,000 people. Miners, engineers, surveyors, cooks and more came to build Colorado River the aqueduct, living in the harshest of desert conditions and Aqueduct ultimately constructing 150 miles of canals, siphons, conduits and pipelines. They added five pumping plants to lift water over mountains so deliveries could then flow west by gravity. And they blasted 90-plus miles of tunnels, including a waterway under Mount San Jacinto.

Management of the Colorado River: Water Allocations, Drought, and the Federal Role
Management of the Colorado River: Water Allocations, Drought, and the Federal Role Updated March 21, 2019 Congressional Research Service https://crsreports.congress.gov R45546 SUMMARY R45546 Management of the Colorado River: Water March 21, 2019 Allocation, Drought, and the Federal Role Charles V. Stern The Colorado River Basin covers more than 246,000 square miles in seven U.S. states Specialist in Natural (Wyoming, Colorado, Utah, New Mexico, Arizona, Nevada, and California) and Resources Policy Mexico. Pursuant to federal law, the Bureau of Reclamation (part of the Department of the Interior) manages much of the basin’s water supplies. Colorado River water is used Pervaze A. Sheikh primarily for agricultural irrigation and municipal and industrial (M&I) uses, but it also Specialist in Natural is important for power production, fish and wildlife, and recreational uses. Resources Policy In recent years, consumptive uses of Colorado River water have exceeded natural flows. This causes an imbalance in the basin’s available supplies and competing demands. A drought in the basin dating to 2000 has raised the prospect of water delivery curtailments and decreased hydropower production, among other things. In the future, observers expect that increasing demand for supplies, coupled with the effects of climate change, will further increase the strain on the basin’s limited water supplies. River Management The Law of the River is the commonly used shorthand for the multiple laws, court decisions, and other documents governing Colorado River operations. The foundational document of the Law of the River is the Colorado River Compact of 1922. Pursuant to the compact, the basin states established a framework to apportion the water supplies between the Upper and Lower Basins of the Colorado River, with the dividing line between the two basins at Lee Ferry, AZ (near the Utah border).
