The data on this page is updated every hour with the assistance of river monitoring gauges provide by the USGS. The monitoring stations are not located at the exact locations where the trails typically flood so blockages such as a log jam, can cause this chart to be slightly inaccurate. It is, however, usually fairly close. If the numbers indicate the trail is close to being flooded (+/- .25 ft), you should assume there is a chance of some water over the trail.

The Sycamore Creek monitoring station is currently intermittently reporting stage levels. Please see http://water.weather.gov/ahps2/hydrograph.php?wfo=grr&gage=hhtm4 if it shows it at 0 in the chart above. Anything above 3.5' is likely to have at least some water over the trail.
Current river levels are updated automatically every hour. If users would like to submit observations to the Facebook page, we will continue to update this site to be as accurate as possible and provide information for all of the common flooded areas.
