What the National Weather Service wrote

Observations of Snow Glacier indicated that a Glacial Dammed Lake (GDL) released on or around the 9/7/23 to 9/8/23. The Snow and Kenai Rivers rose rapidly in response, routing flood waters through the system from the GDL. The Snow River reached action stage, however as the flood propagated downstream it combined with high river baseflows to crest in minor flood at 13.48 feet at 3:15pm AKDT on 9/10/23 at the Cooper Landing river gauge.
