Real-Time Hydroelectric Dam Monitoring

Hydroelectric dams provide clean and renewable energy to the grid, which is sorely needed in regions that rely heavily on fossil fuels. While the dams utilize a renewable resource that will remain viable as long as the waterway flows, they still put a strain on the environment.Dam monitoring can take many forms, but most hydroelectric facilities are required to monitor conditions above and below that dam to ensure that conditions meet ecosystem needs. When successful, dams can operate for many years with limited impacts on the surrounding system.It’s the job of environmental professionals like Craig Goldinger, a regional manager with Eagle Creek Renewable Energy in Western Pennsylvania, to oversee monitoring efforts above and below the dams and adjust operations to protect resources while continuing to provide power to the public. Challenge: Building a Reliable Monitoring System for Hydroelectric Plants

Remote Water Quality Monitoring in Oklahoma

Water is integral to all aspects of life, yet many people neglect to consider where their water comes from. Whether it is used for drinking or recreating, water feeds human and natural resources in the watershed. In order to protect all of the interconnected resources, keeping aquatic systems healthy is necessary, according to Sarah Dexter, an Environmental Program Supervisor with the Oklahoma Water Resources Board (OWRB).Dexter’s work primarily focuses on monitoring the influence of stormwater in Norman, Oklahoma, as well as overseeing the monitoring of the Grand River Dam Authority’s (GRDA) dissolved oxygen monitoring program. Both programs have the ultimate goal of protecting natural resources from human-caused damages and preventing drastic environmental changes that could reshape surrounding systems. Challenge: Meeting Environmental and Data Requirements The main challenge facing the GRDA project was the need to gather data in real-time in order to allow resource managers and dam operators enough time to respond to possible threats to water quality. The system must also be equipped with all of the necessary equipment to quickly and efficiently gather data on the water below the dam.

Sediment Monitoring During the Klamath Dam Removal

Sediment Monitoring During the Klamath Dam Removal

Sediment Monitoring During the Klamath Dam Removal

Leading up to the 21st century, the United States supported decades of dam construction in major waterways across the country. Many of these dams were hydroelectric facilities built in order to provide energy to nearby towns and cities. Unfortunately, these dams deteriorated the surrounding environment and harmed aquatic life.Many of these dams cut off migration routes for migratory fish like salmon and created reservoirs above the dam. These reservoirs are typically filled with still water that warms quickly over the summer, leading to declines in water quality and increases in algal blooms which, in turn, worsens the water quality further and impacts habitat suitability.For many dams, like the Klamath Dam in Washington, the cost of maintaining these facilities has outweighed any potential benefits they may have once provided. As a result, dams are being removed across the country in order to restore natural waterways and reopen critical pathways for fish migration. Challenge: Monitoring Dam Deconstruction
