Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. The software lies within System Tools, more precisely Dashboard Widgets. This free Mac application is a product of Adam Franco.
From the developer:
RiverLevels is a dashboard widget that provides an easy way to monitor the amount of water flowing in your favorite streams and rivers. The application is of particular interest to whitewater kayakers and canoeists. Once any United States Geological Survey (USGS) stream-gauge station is selected, it is automatically refreshed to always provide you with the latest graph of the water level.
You may want to check out more software for Mac, such as Sable Maze: Sullivan River, Fear for Sale - The House on Black River CE or River Raider: Retaliation, which might be related to River Levels.
