Winter sampling in Fish Creek Estuary

SAWC staff, joined by ADF&G Habitat Biologists, visited the dredge ponds in Fish Creek estuary, near Douglas, AK, to assess watershed enhancement opportunities in the area. To learn more about current habitat conditions, we measured water quality and trapped overwintering fish in both ponds. The east pond was completely iced over, but dissolved oxygen concentrations were high, and many stickleback and even a few juvenile Coho appeared in the fish traps. In the west pond, which is connected to Fish Creek and tidally influenced, we found many juvenile Coho, stickleback, sculpin, and even a shrimp in the fish traps. Water quality measurements indicated high dissolved oxygen concentrations and a mix of freshwater and salty, tidal water in the west pond.
