The Science of Measuring Water Levels at Lake Mead


Understanding the science of measuring water levels at Lake Mead is crucial due to its significant impact on water management in the surrounding areas, including Las Vegas. The Reclamation Bureau working alongside the USGS water resources division, has established a sophisticated system to monitor these water levels to ensure that they have accurate and up-to-date information. This becomes more important as Lake Mead’s levels have seen fluctuations due to various factors, including climate change and usage demands.

How Many Gauging Stations Are at Lake Mead process of measuring water involves a combination of traditional gaging stations and high-tech tools like satellite altimetry. Gaging stations around Lake Mead, especially those near Hoover Dam, serve as critical checkpoints for observing water fluctuations. These stations are equipped with instruments to record the water levels, and then this data is used to make decisions regarding water allocation and conservation strategies. The Reclamation Bureau invests in these stations as they are a cornerstone in predicting potential water shortages or planning for future water usage.

Gaging Station Locations


Station 09404200, Colorado River above Diamond Creek near Peach Springs, AZ, is located near the lower end of the Grand Canyon 130 miles upstream from Hoover Dam; both water gains and water losses are expected as the Colorado River flows through the Grand Canyon, but no significant tributaries enter the Colorado River below Diamond Creek so this station should still provide a reasonably good estimate of inflow to Lake Mead. Available and estimated flow data since July 2002, when the Las Vegas Wash station resumed operation, indicate the Colorado River is currently contributing about 96.9% of the flow to Lake Mead.

The Virgin River at Littlefield, AZ (09415000) and Muddy River near Glendale (09419000) stations have historically been used to describe inflows to Lake Mead because of their long periods of record. Station 09415000 is located 58 36 miles upstream of Lake Mead and Station 09419000 is located 16 miles upstream of the lake. Both of the stations significantly overestimate inflow to Lake Mead because agricultural operations between the gages and the lake divert almost the entire flow of both rivers during the summer months. As a result, many previous reports attribute too much flow to these two tributaries.

Two lower stations, 09415250, Virgin River above Lake Mead near Overton, NV, and 09419507, Muddy River at Lewis Avenue at Overton, NV, were installed more recently and are located 4.2 and 5.75 miles, respectively, upstream of Lake Mead to give a much better indication of actual inflows. These stations have only operated for short periods and records are not continuous, but flow data clearly show the impacts of the diversions.

Flows at the downstream Overton, NV, station on the Virgin River averaged 67% of the upstream Littlefield site (range = 0-129%) and the downstream Lewis Avenue site on the Muddy River averaged 40% of the upstream Glendale site (range = 17-53%). Due to falling water levels, the Virgin and Muddy Rivers have been entering Lake Mead as a combined inflow since July 2009.

Satellite altimetry, on the other hand, provides a broader perspective by measuring the water levels of Lake Mead from space. This technology allows scientists to measure the height of the water surface from satellites orbiting the Earth.

By comparing these measurements over time, experts can identify trends in water level changes. This technology complements the ground-based measurements taken by the gaging stations, giving a more comprehensive view of the health and status of Lake Mead’s water resources.

The cooperation between the Reclamation Bureau and the USGS water divisions underscores the significance of accurate water level measurements of Lake Mead.

The data collected from both the gaging stations and satellites are invaluable for researchers, policymakers, and the general public. The process also involves ongoing maintenance and calibration of equipment to ensure that data is reliable. These measurements of water levels guide important decisions regarding water supply safety and sustainability in the region.

In conclusion, accurately measuring the water levels at Lake Mead is a complex science that incorporates the use of both on-site gaging stations and advanced satellite altimetry. The dedication of the Reclamation Bureau and USGS water teams to this task is vital for the management of one of the country’s largest reservoirs. As the pressures on Lake Mead’s water resources continue to grow, so too does the importance of precise and reliable measurements.

Gaging Stations Data Analysis and Satellite Altimetry


Gaging stations at Lake Mead are crucial for monitoring the lake’s health, providing essential data on the water levels and quality. These stations are part of a network managed by the United States Geological Survey (USGS) and contribute to a large databank known as USGS water data. The information they gather is valuable for understanding the dynamics of the lake area, including the storage capacity and the surface area changes over time. This data becomes particularly relevant when we consider Lake Mead’s position within the river basin it occupies, serving as a barometer for the conditions of the Colorado River.

(Satellite Altimetry)-dedicated satellites are equipped with a sensor, which transmits microwave pulses in the radar frequency domain or laser pulses in the optical or infrared domain to the ground and receives the return signals after reflection at Earth’s surface. Because of the favorable reflective properties of water, the radar observation technique is especially suitable over oceans and open water on land. The primary measurement is the satellite-to-water surface round-trip travel time of the signal, multiplied by the speed of light, is equivalent to the round-trip distance. Thus, the range, or distance between the satellite and the instantaneous sea surface is approximately equal to one-half of the two-way travel time multiplied by the speed of light.

Satellite altimetry is another sophisticated tool that complements the traditional gaging stations. By using satellites to measure the time it takes for a radar or laser signal to bounce back from the surface of the lake, scientists get accurate readings of the surface area of Lake Mead. This helps in confirming the data collected by ground stations and provides a more comprehensive picture of the lake’s water levels.

Detailed analysis of the USGS data can reveal patterns in water year trends, which are critical for water management in the Colorado River basin and central Arizona. By understanding these trends, authorities can make better decisions about water use and conservation efforts. Moreover, the data from Lake Mead helps to determine how much water flows downstream to sustain communities and ecosystems reliant on the Colorado River.

Throughout the year, as evaporation, rainfall, and human consumption affect Lake Mead, its storage capacity and surface area fluctuate. These changes are measured in feet (ft), and the data provides insights into how much water is lost or gained during different seasons. This information is particularly useful for predicting water availability and for planning purposes.

The synergy between gaging stations and satellite altimetry ensures that water data is accurate and reliable. It allows for a more nuanced understanding of the water dynamics within Lake Mead, affecting millions of people who depend on it. As water levels in Lake Mead have been of significant concern in recent years, due to prolonged droughts and overuse, this data has become a lynchpin in managing the scarce water resources of the region.

In conclusion, Lake Mead’s gaging stations and satellite altimetry offer a dual approach to monitoring the lake’s condition. They not only provide a wealth of water data but also ensure that the data is precise. This comprehensive strategy is key to managing the lake’s resources, which is a significant component of the Colorado River system that sustains life in central Arizona and beyond. In essence, such diligent analysis of data sustains the intricate balance of nature and human necessity, keeping the lifeblood of this arid region flowing continuously.
