Homeowners along the Kenai River fight rising flood waters
The Kenai River has been running high ever since two glacier dammed lakes emptied into the river over the last few days. In the Kenai Keys subdivision near Sterling, the river is lapping at the doorsteps of the hundred or so homes that line the river. Longtime resident Frank Turpin said although he’s seen worse flooding, this one is significant. The road leading into the gated subdivision is flooded in numerous places although some vehicles can still make it through. Neighbors who live on higher ground have offered their yards for people wishing to store cars or other items until the waters recede.

The Western Arctic Caribou Herd has been declining for years, and the migration patterns of the animals have been changing. In several locations in Northwest Alaska, caribou have been arriving later and later in the season. Friday last week, people in Kotzebue finally started seeing caribou — hundreds of them ― crossing the Kotzebue Sound north of town, coming from the Noatak riverside. Ice conditions are one of the reasons for the caribou’s late migration, said Thomas Baker, chair of the Northwest Arctic Subsistence Regional Advisory Council.

Hunters report record harvest for Central Southeast moose hunt
Hunters in Central Southeast Alaska have reported a record harvest of 141 bulls during the month-long moose hunt, surpassing the previous record of 132 bulls set in 2021, with the majority of the harvest occurring on Kupreanof Island.

But over the years, he said he’s seen more moose cropping up on remote islands.
