Water Level, Temperature, and Discharge of Headwater Streams in the Noatak and Kobuk River Basins, Northwest Alaska, 2015-2017

This data set includes 15-minute interval data on stream temperature, stage, and discharge from low-order streams in the Noatak and Kobuk River valleys in Northwestern Alaska, collected during the summer months. Several sites in the Agashashok River basin were monitored in 2015 and 2016, and additional sites were added in 2017. The depth of the water and temperature were determined using a combined pressure transducer and temperature sensor that was deployed through the summer months. Different sensors were used in each stream and year, so a file is included detailing the stage and temperature accuracy for each year and stream. In rare instances in the fall, stage was estimated for certain streams (e.g. NFT3) based on remote camera images of the staff plate. Discharge was derived from the stage data by creating a rating curve relating stage to discharge measured during site visits.
