These lidar data were collected on September 27, 2005, for the
NOAA Fisheries Service - Northwest Fisheries Science Center as part of the
ISEMP (Integrated Status and Effectives Monitoring Program) for the Columbia Basin. Data collection and processing were performed by
Watershed Sciences. The flight covered 122 km
2 and 26 river kilometers of
Bridge Creek, a tributary to the John Day River in central Oregon. The flight was used as a baseline survey for the Bridge Creek
Intensively Monitored Watershed, which is nested in the broader
Status and Trend Monitoring in the John Day Pilot Basin.
Channel incision within Bridge Creek IMW, OR, has degraded instream and floodplain habitat leading to a loss of spawning and rearing habitat, increased summer stream temperatures and reduced base flows impacting steelhead using this system. ISEMP is collaborating with the
National Park Service, NOAA-Fisheries, and the
Bureau of Land Management on a restoration project that will accelerate natural recovery rates of the processes that create and maintain steelhead habitat to substantially increase steelhead productivity within the drainage.
