This data set includes 15-minute interval data on stream temperature, stage, and discharge from low-order streams in the Yukon River Basin in interior Alaska, collected during the summer months. 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. Discharge was derived from the stage data by creating a rating curve relating stage to discharge measured during site visits.

This dataset 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.

This dataset includes 15-minute interval data on stream temperature, stage, and discharge from an upstream and downstream gaging location on West Twin Creek, a first-order tributary to Nome Creek in the White Mountains of Alaska.

This data release contains measurements from continuous monitors of stream temperature, groundwater temperature, and well water levels, and discrete measurements of discharge and stream shading.

This data release contains inputs for and outputs from hydrologic simulations for the Alaska (AK) domain using the Precipitation Runoff Modeling System (PRMS) version 5.2.1.1 and the USGS National Hydrologic Model infrastructure (NHM, Regan and others, 2018). These data document the PRMS output data files for the precalibration,byHRU and byPOIobs release runs for the AK domain produced for the period 1980-2021. Each .zip folder contains 15 NHM-PRMS output variables, in NetCDF format, for each simulation's release run. Water-Budget Files with the model-domain summary table of the AK domain are also included in this child item (Markstrom and others, 2015; Hay and others, 2023). The main landing page provides additional information and a data dictionary (output_variables_data_dictionary.csv) which describes the selected output variables. CONTENTS OF THIS CHILD PAGE: 1. AK_byHRU_NHM_PRMS_data_release.out = AK byHRU annual water balance summary 1980-2021. 2. AK_precal_NHM_PRMS_data_release.out = AK precalibration annual water balance summary 1980-2021. 3.
