The River Watch team reports that the breakup front on the Kuskokwim River is stalled at the mouth of the Johnson River, with strong, intact ice extending downstream. Upstream ice is backing up tightly to just below Napakiak, where water levels rose Thursday afternoon, encroaching on low-lying roads and structures. Minor flooding of these areas of Napakiak is likely. Backwater from the ice jam is also elevating water levels upstream to Bethel, reaching bankfull conditions and pushing water and ice into Brown's Slough. Minor flooding is possible overnight in low-lying areas around Brown's Slough, including Alligator Acres, especially during high
Hydrologic Outlook issued May 8 at 4:03PM AKDT by NWS Anchorage AK
ESFAFC As of late Thursday afternoon, heavy floes of ice are working their way downstream on the Kuskokwim River from near Bethel to Napakiak. Water levels are high to near bank full as these runs of ice move downstream; however, flooding is not anticipated as downstream ice has been rapidly weakening over the past several days down to the mouth of the Johnson River. Per observation, area sloughs and Kuskokwim River tributaries are also taking some of the ice to relieve stress on the Kuskokwim. NWS and the River Watch team will continue to reach out to local community members
