Click HERE for additional information including a current list of streamgages with upcoming datum changes. This update in gage datum does not affect the location of the streamgage, nor the observed local gage height or discharge recorded at the streamgage.

with a full decommission expected 6 months later. Learn more about the upcoming change and where to find the new samples data in our blog.
