Fontenelle Dam Releases & Green River Flow Updates

1966 Telephone Island 2-512x219We will post upcoming flow changes as they become available, with the link to Fontenelle Dam daily release information.  Large boulders, rock sills and structures in the river bed pose a constant risk to boaters on this stretch of the Green.  High water has the potential to drastically alter instream characteristics, such as locations of gravel bars, riffles and holes.  Float times during high water can also be expected to decrease.  Low flows will reveal more obstacles for boats and longer float times.  Visitors should be aware of changing flows and the associated risks.
