5 Easy Steps to Flood Water Information

To monitor the Gilboa Dam at Schoharie Creek for flooding follow these 5 easy steps.

Step 1:
Check the Hydrograph for Gilboa Dam Water Levels page.

Print out the "Live" hydrograph so you can make a comparison the next time you check. The "Live" hydrograph shows the Schoharie Creek at Gilboa Dam water level changes over time.

Step 2:
Check the Water Flow Data page.

The U.S. Geological Service provides Real-Time Water Flow Data or "Live" sites that "transmit data to the web database, every 1 to 4 hours". The Live Water Flow Data informaton includes; Discharge, cubic feet per second and Gage height, feet information.

Step 3:
From the Water Flow Data page select
Real-Time Water Flow Date for New York: Streamflow Index . Print out for later comparison.

Step 4:
From the Real-Time Water Flow Date for New York: Streamflow Index page
Scroll down and highlight "Schoharie Creek at Prattsville"...Water going into the reservoir...
Scroll down and highlight "Schoharie Creek at Gilboa"...Water going out of the reservoir.

Comparing this water flow information every hour will tell you how fast the water is rising.
When inflow starts to decrease at Prattsville, it has "crested" there and even though it continues to increase and crest along the way as it travels North, you can begin to breath a sigh of relief providing it is not at an emergency flood level stage.

The last USGS gauge station is at Breakabeen so you need to keep in mind that tributaries will affect the amount of water flowing North and do play a big role in raising the Schoharie Creek.

Step 5:
