Welcome to the Lake Powell and Glen Canyon Dam update for May 2024! In this episode of timeBomb, we're bringing you the latest news and crucial updates on America's second-largest reservoir, Lake Powell, and its critical infrastructure, the Glen Canyon Dam.
Lake Powell Water Level Update:
We start with an in-depth review of Lake Powell's water level, currently standing at 3561 feet 11 inches above mean sea level. This is an increase of 3 feet 8 inches since our last update. Despite this rise, the reservoir remains 66 feet below the historical average for this date and 138 feet below the full pool elevation. We'll analyze the factors contributing to these changes, including reduced water deliveries to the Lower Basin states and the impact of the melting snowpack from a second consecutive year of above-average winter precipitation.
Historical Context and Current Status:
We'll provide a historical perspective, comparing the current water level to Lake Powell's record high set in July 1983 at just over 3708 feet and its record low set in April 2023 at 3519 feet. The reservoir is currently only 32.58% of full capacity, highlighting the ongoing challenges despite recent gains.
Lake Mead Status Update:
Since Lake Powell and Lake Mead are jointly managed, we'll also cover Lake Mead's current status. The water level at Hoover Dam’s reservoir has seen fluctuations, with a notable increase between December and March, followed by a steady decline to the current elevation of 1070 feet. We’ll discuss the implications of reduced outflows from Glen Canyon Dam on Lake Mead’s water levels and future trends.
Glen Canyon Dam Plumbing Issue:
The episode takes a deep dive into a disturbing new report of damaged plumbing inside the Glen Canyon Dam. Federal officials have identified damage within the dam’s four 8-foot-wide steel pipes, known as the river outlet works, which have suffered from cavitation. This damage could have severe consequences for the 40 million people who rely on the water and power delivered through the dam. We'll explain the potential impact on water delivery, the laws governing the Colorado River, and the urgent need for a major overhaul or replacement of these critical pipes.
Implications and Future Outlook:
We'll discuss the potential ramifications of the damaged pipes on both Upper Basin and Lower Basin states, including the possibility of reduced water deliveries and legal challenges. The Bureau of Reclamation’s plans to maintain Lake Powell’s elevation above the minimum power pool and the possible measures to achieve this goal, such as releasing water from upstream reservoirs or reducing usage, will also be covered.
This is an evolving story with significant implications for water management and infrastructure in the Western United States. Stay tuned as we bring you the latest developments and expert analysis.
