Lake Powell is disappearing. And if you’re not paying attention to the data on the water levels in Lake Powell, you’re missing the narrative of one of the most important – and most contested – reservoirs in the American West. The Lake Powell Water Database allows an uncommon and real-time view of the health of the reservoir, providing everything from the changes in elevation to the temperature changes. This post provides an overview of what the database does, how to access the data, what data it provides, and why it has become a reliable resource for environmental professionals, policymakers, and concerned citizens alike.
What Is the Lake Powell Water Database?
The Lake Powell Water Database is a free-to-use interactive website that serves as a repository of extensive hydrology data for Lake Powell. Lake Powell is the second largest artificial reservoir in the United States. Managed through Water-Data.com, the database compiles measurements taken daily—sometimes hourly—about the lake’s physical and environmental condition.
Key Features:
- Date Measured: Time-stamped entries of all available data.
- Elevation: Lake surface elevation in feet above sea level.
- Change: Day-to-day elevation changes.
- Content: Water volume, expressed in acre-feet.
- Inflow/Outflow (cfs): Cubic feet per second of water entering or exiting the lake.
- Temperature Data: Includes high and low air temperatures and water temperature.
This dataset is vital for water managers looking to allocate resources under the provisions of Colorado River Compact and for researchers studying drought patterns, climate change impacts and ecosystem health.
Why the Lake Powell Water Database Matters More Than Ever
Lake Powell is not just a scenic destination—it’s a lifeline. Formed by the Glen Canyon Dam on the Colorado River, it serves water to over 40 million people in seven U.S. states and Mexico. Yet its levels have plummeted in recent decades due to overuse, sustained drought, and rising temperatures.
Real-World Impacts:
- 2021: Water levels dropped to 3,554.5 feet—below the threshold for hydroelectric power generation at Glen Canyon Dam (minimum power pool: 3,490 feet).
- 2022: Emergency releases from upstream reservoirs like Flaming Gorge were implemented to prop up levels.
- 2023: Brief rebounds in elevation were observed due to high snowpack, but did not reverse the long-term decline.
These shifts are more than just numbers—they affect water security, agricultural viability, and energy stability across the Southwest.
How to Use the Lake Powell Water Database Effectively
Using the Lake Powell Water Database doesn’t require specialized knowledge, but understanding a few core elements will help you gain meaningful insights.
Step-by-Step Guide:
- Start at the Main Dashboard: lakepowell.water-data.com
- Explore the Interactive Charts: Hover over each point for daily values.
- Check Data Boxes: Above the graph, users can filter by date range, variable (e.g., inflow), or metric.
- Scroll to Bottom for More Data: Use the dropdown menu under “Search DB For More Water Data Facts” to explore historical datasets, back to the 1960s.
Expert Tip:
Use the combination of inflow and outflow to calculate net change. For example, if inflow is 10,000 cfs and outflow is 12,000 cfs, the reservoir is losing water—critical for planning purposes.
Case Study: Monitoring a Critical Low in 2022
In June 2022, Lake Powell hit one of its lowest points in history. By querying the database for June 10–15, users could see a sharp inflow-outflow imbalance:
- Inflow: ~6,000 cfs
- Outflow: ~8,500 cfs
- Water Temp: ~76°F
- Elevation Loss: 2.3 feet over five days
This snapshot helped journalists, researchers, and emergency planners communicate the urgency of federal intervention.
Who Uses the Lake Powell Water Database?
The database has become indispensable for a range of users:
- Environmental Scientists: For tracking ecosystem response to changing temperatures and water levels.
- Policy Makers: For real-time data to inform water allocations and emergency drought response.
- Journalists: For sourcing reliable, historical data in environmental reporting.
- Local Residents & Tourists: To monitor recreational water levels and safety.
Additional Insights: What Lies Beyond the Graphs
Clicking through the dropdown menu at the bottom of the site unveils a wealth of extended data sets:
- Historic Extremes: Lowest and highest levels by year
- Average Monthly Temperatures: For correlating weather with water storage trends
- Climate Projections: While not native to the database, these can be paired with NOAA or USGS data for predictive modeling
This added context empowers deeper research and long-term water planning.
Practical Tips for Long-Term Monitoring
- Bookmark the Page: Daily updates make this a valuable tool for trend monitoring.
- Export Screenshots for Reports: Charts are clean and can be used in presentations.
- Use in Conjunction with Other Tools: Combine with the Colorado River Basin Forecast Center for a broader hydrological perspective.
- Monitor Temperature Trends: Rising water temps can signal shifts in aquatic ecosystems.
Final Thoughts: Data That Drives Decisions
The Lake Powell Water Database is not only a scientific tool, it is a civic resource. As climate pressures increase and water conflict increases, data, especially data that is available in a real-time and accessible format, allows stakeholders at all levels of engagement to make informed decisions.
Whether you are a scientist, policymaker, or interested citizen, how you interpret this data will, in part, impact the ways in which you and we will adapt to a drier future.
