Subject: Changes to flood stage categories for the Shunganunga Creek
         at Topeka, KS.

Beginning on Tuesday, June 2, 2025, all flood stage categories for
the Shunganunga Creek at Topeka, KS at 21st Street, TSHK1, will be
lowered. Recent review of past floods indicated that flooding
occurred at lower stages than the existing flood categories. In
order to represent the flood impacts more accurately along the
Shunganunga Creek, the flood categories will be lowered. These
changes have been coordinated with the USGS and Shawnee County
Emergency Management.
