Evaluating Microbial Nutrient Sediment Dynamics in Lake Erie Watersheds

Evaluating Microbial Nutrient Sediment Dynamics in Lake Erie Watersheds A primary goal of water quality managers is to intercept or mitigate nutrients or pathogens at their source to ensure effective wastewater treatment. Source water treatment includes building onsite treatment systems and implementing agricultural best practice for crops. To ensure mitigation is working, managers often monitor nutrients and pathogens in water.…

Evaluating stationary hydroacoustics for determining fish movement and abundance

Evaluating stationary acoustics Little is known about the large-scale movement patterns of Great Lakes fishes. Though it is understood that large migrations of fish typically occur along regions of Lake Superior during spawning events, the timing and potential drivers of these events are not well understood. Better understanding the timing and drivers of these events is important for more effective management of these fisheries. ...

Black Bay Walleye Acoustic Telemetry

Black Bay Walleye Ice Fishing Located on the north shore of Lake Superior, Black Bay historically supported a robust commercial and recreational fishery for walleye (Sander vitreus). Unfortunately, the walleye population rapidly declined in the 1960s because of a combination of habitat loss and commercial over-fishing. In response, managers closed the fishery in the northern part of Black Bay to allow the population to recover. ...

Using the REASON (River Environment And Sensor Observation Network) Project to Support Adaptive Management of the Saint Lawrence River

Aerial view of Moses Saunders Power Dam A regional water problem is the paucity of data to support policy decisions on water quality in the International Section of the St. Lawrence River. One cost-effective method to alleviate this information gap is to use remote continuous observation water quality sensor arrays. A novel application that we have developed is the installation of sensor arrays in a hydropower dam wherein ...

Monitoring flood water in the Detroit River

Monitoring flood water in the detroit river Great Lakes water levels have reached record highs in 2019, eroding shorelines, threatening and damaging public/private infrastructure (e.g., marinas, homes and cottages), and overwhelming water systems in communities. On July 7, 2019, strong winds from the northwest pushed Detroit River water above the storm water system in Lasalle, Ontario, resulting in significant flooding, closure of streets, and limiting access to homes, public spaces (closed swimming pools and sport fields) and many businesses.…

During early summer and fall of 2019, RAEON deployed three real-time buoys equipped to measure weather and water-quality parameters, including dissolved oxygen, in Lake Erie near Pelee Island. These buoys will collect data that will predict the location and movement of oxygen-depleted, or hypoxic, water in Lake Erie, a source of drinking water for millions of people in northwest Ohio.…
