FLIR/Day TV image ( frame: nfn0477 ) showing the NF Nehalem River at the fish hatchery

FLIR/Day TV image pair (frame: neh0070) showing the confluence of Bob's Creek (16.8 deg C) and the Nehalem River (18.9 deg C) at river mile 3.6. The Nehalem River flows from the top to bottom of the image and Bob's Creek flows in from the left side. The thermal plume of Bob's Creek flows up-stream indicating an incoming tide.

FLIR/Day TV image pair (frame: neh0410) showing the confluence of the Nehalem River (21.6 deg C) and Lost Creek (16.8 deg C). Lost Creek is visible flowing in from the right side of the image.

FLIR image mosaic (frames: neh2196 to neh2200) showing the confluence of the Nehalem River (23.4 deg C) and Fishhawk Creek (21.9 deg C) and Beaver Creek (18.7 deg C). Fishhawk Creek flows in from the bottom left of the image and Beaver Creek flows in from the upper left of the image.

FLIR/Day TV image mosaic (frames: neh1126 to neh1130) showing the confluence of the Nehalem River (23.2 deg C) and Quartz Creek (16.6 deg C). Apparent thermal heterogeneity observed at the stream surface may indicate partial thermal stratification in this reach.
