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.

Western Arctic Caribou Herd shrank more in 2022, hurting Northwest Arctic subsistence hunters
Biologists struggle to single out a leading cause of the caribou population’s decline.

Fish die off near Kotzebue
Ali Ralson was riding her 4 Wheeler towards Cape Blossom and came upon a beach full of fish. It appears that most of the fish are stickleback although there may be other species involved too. This would suggest an environmental issue that would impact multiple fish species rather than a pathogen. One potential cause could be harmful algal toxins.

Community Water Distribution System Freeze Up
We performed a survey of community water lines to see how permafrost thaw and sinking foundations may be impacting homes, water and waste water systems. During the June visit we saw where foundation sinking was putting stress on pipe runs and junctions. Now in the winter we see evidence of freeze up in some of the homes where the junction boxes have been compromised, gaps in the insulation seal, and resulting freeze up and overflow of water.
