Subject: Change in Gage Zero Elevation for Honeoye Creek at Honeoye
         Falls (HNYN6)

Effective April 1, 2019 the National Weather Service (NWS) will
change the official flood stages and historical crests at the
Honeoye Creek official forecast point at Honeoye Falls. The minor,
moderate, and major flood stages will be change from the current
stages of 4.5, 5.0, and 6.0 feet respectively to 6.5, 7.0, and 8.0
feet.

The river gauge is owned and operated by the New York United States
Geological Survey (USGS) and the United States Army Corps of
Engineers (USACE) in Buffalo. Due to periodic negative river stage
readings, it was determined that the zero datum, or starting point
for river stage readings, should be lowered by two feet. The impacts
of this change will be an adjustment of two feet to all NWS defined
flood stages. The historical river crests displayed on AHPS will
also be adjusted by two feet for consistency.
