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

Tracking Flow For Hydropower

Tracking Flow For Hydropower

Tracking Flow For Hydropower

The Northern Indiana Public Service Company (NIPSCO) is a large energy provider in the state of Indiana. It provides power to more than a million customers through distributing energy derived from natural gas and hydropower dams.As part of achieving its mission to provide reliable energy to its customers, officials at the company have to be aware of changing flow rates near its hydropower assets. The real-time calculations are necessary for keeping plant managers up to speed on factors that could influence hydropower output.To meet the need for quality data tracking flow, officials at NIPSCO contracted engineers at LimnoTech, an environmental consulting company based in Ann Arbor, Michigan, to devise a monitoring solution. Project managers at LimnoTech then collaborated with specialists at NexSens Technology to equip vital hydropower areas with water level sensors and cellular data loggers. Going with the flow

Great Lakes Buoy Networks

Great Lakes Buoy Networks

Great Lakes Buoy Networks

The Great Lakes region is a dynamic ecosystem that supports millions of people, plants and animals. Key to maintaining its vitality is making sure the waterways that sit at its base remain clean and healthy. To do that, scientists and water managers need steady, reliable data. They often get this information from buoy networks.There are many different Great Lakes buoy networks out there, which are largely supported by government agencies and universities. Maintaining these networks, including servicing old buoys or launching new ones, is a big and important job.In one example of the ongoing work to support buoy networks, researchers with the University of Wisconsin launched two new monitoring buoys to track a variety of water quality parameters. The new platforms contribute data to the National Data Buoy Center, Great Lakes Observing System (GLOS) and the University of Michigan’s Ocean Engineering Lab.
