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 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.

A combined soil water balance, groundwater flow and stream temperature model was developed to simulate stream temperature under historical and future conditions. Soil-Water-Balance code was used to estimate net infiltration past the root zone and surface runoff, which were applied to a transient, three-dimensional MODFLOW 6 model to simulate the water budget for Beaver Creek and the contributing groundwater flow system at a 7-day time resolution. Instream temperatures were simulated using a Stream Network TEMPerature (SNTEMP) model based on the Streamflow Routing (SFR) Package network and simulated groundwater discharge and surface runoff from the MODFLOW model. Model parameter estimation was performed via history matching of groundwater levels, instream flows and stream temperatures for 2019–2023. Future climate scenarios were developed using an initial spin up 2019-2023 period and then downscaled data from the Scenarios Network for Alaska and Arctic Planning (SNAP) for 2023-2050 This data release is split into 6 child items so that a user can choose which portions of the model archive to download to avoid downloading large model files that are unnecessary for a particular use. An overview of the contents of each child item and complete instructions for downloading the model input and output files, running the model, and running the python scripts used to build and update the model are provided in the parent_beaver_creek_readme.md file at the main level of this data release and the readme.md files provided with each data release child item.

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 data release includes remotely sensed lake and lake chemistry and water temperature data collected from 2011 to 2014) from a series of lakes on the Arctic Coastal Plain of Alaska. Most of the data is from two sites within the Chipp River Basin.

A historical conditions MODFLOW6 and SNTEMP model was developed to simulate groundwater flows and instream temperatures in Beaver Creek, Alaska during the study period and time just prior to the study. Model parameter estimation was performed via history matching of groundwater levels, instream flows and stream temperatures for 2019–2023. This data release contains a version of the historical model built from the best parameter set generated during the history matching. The history matching and model development workflows are archived in the "Groundwater flow and SNTEMP stream temperature model build and history matching workflows" child item associated with this data release. The version of the model included in this child item is the version that was used to generate the historical model results presented in the associated publication "Simulating present and future Groundwater/Surface-water interactions and stream temperatures in Beaver Creek, Kenai Peninsula, Alaska". This data release includes the model input files, executable files, and output files for that historical model.
