This data repository holds modeling inputs and output from a project that compared various restoration and management actions influence on stream temperature. Three study systems were used in this effort that include the Middle Fork John Day River, South Fork Nooksack River, and Wind River basins of Oregon and Washington states in the USA. The spatial stream network (SSN) models used in this project were previously developed and published in the Journal of American Water Resources Research (doi: 10.1111/1752-1688.13158). These models were used to make predictions in each study basin that reflected restoration and management goals within each system. The predictions for temperature changes were then compared individually as well as in a combined management activity scenario. This repository holds the input data for the SSN models as well as the prediction output from each modeling scenario for each basin.
