Subject: Changes to Flood Stage Categories for the Gunnison River at 
Delta, CO (DELC2).

Effective June 19th, 2026, NWS flood stages at the Gunnison River at 
Delta, Colorado will change. Flood surveys, HEC-RAS modeling, and 
coordination with local officials and emergency management indicate 
lowering flood stages at all categories will more accurately 
represent the levels when impacts begin near Delta, CO. River 
forecasts will now be issued when water levels are expected to reach 
or exceed 8.5 feet, and Flood Warnings will be issued when water 
levels are expected to reach or exceed 9.0 feet. 

Category:	Current Stage:		New Stage: 
Action 		9.45 feet		    8.5 feet 
Minor		12.0 feet		    9.0 feet 
Moderate    14.0 feet		    10.0 feet 
Major       15.0 feet		    10.5 feet
