RainWise Weather Stations, Telemetry And Accessories
RainWise is one of the oldest players in the weather monitoring market, having been around since 1974. For reference, that’s only 4 years younger than the U.S. Environmental Protection Agency. 
 
Through the years this Maine-based company has logged several advancements in the field starting with RainWise’s very first product, the tipping bucket rain gauge, which is now an industry standard. Since then they have introduced the first consumer digital weather station and the first wireless consumer weather station among other pioneering innovations. 
 
With more than 40 years of experience, the products that RainWise produces today are just as inspired.

A multi-disciplinary team at Miami University, Ohio, has been studying the environmental change at Acton Lake for over three decades. Using three different NexSens buoys over this time, the team has an incredible archive of data that is helping build a picture of Acton’s past, present, and future. 
 
Until recently, a NexSens CB-50 buoy was used alongside other environmental monitoring at Acton Lake. In May 2025, the Miami team deployed a new XB-200 buoy , future-proofing their ongoing monitoring using real-time buoy systems. 
 
Acton Lake, a small hypereutrophic reservoir in southwest Ohio, covers 2.4km² and has a maximum depth of about 8m. The dam was built in 1956, and the lake has a large agricultural watershed.

Thousands of US cities pull their drinking water from natural source waters like reservoirs, rivers, and streams, making overall watershed health a key consideration for water providers. In Albany, New York, the Albany Department of Water and Water Supply delivers drinking water to over 100,000 residents as well as monitors and manages the larger drinking water supply watershed. 
 
Hannah Doherty, Environmental Specialist at the Albany Department of Water and Water Supply , spends her days working with a small team to monitor the drinking supply and the connected water bodies. 
 
Doherty explains, “We’re the first to encounter the water that ends up being the drinking water.
