Impact/Purpose:
This work is a part of a larger effort to develop a fine-resolution spatial stream network (SSN) temperature model for the mid-Atlantic region of the U.S that can be used by tribes and regional partners to address temperature issues in the region's watersheds. In many larger stream and river networks, particularly the Chesapeake Bay Watershed, there is a need to update water quality standards for temperature, focus conservation and restoration activities to protect cold-water streams for sensitive species like native brook trout, and continue analyses and mapping/modeling to identify stream reaches with thermally resilient groundwater inputs to focus habitat restoration efforts. This subproduct includes the input data, output data (i.e., results), and metadata that accompany EPA's CBW-cont-stream-temp-QC program (USEPA/CBW-cont-stream-temp-QC). With the input data, the user has the ability to reproduce the results of the CBW-cont-stream-temp-QC R program, providing method and data-transparency. The results, which include QC-aggregated site information, daily stream temperature metrics, and monthly stream temperature metrics were created for the development of a high-resolution statistical stream network (SSN) temperature model based on the NHDPlusHR flowline network; however, the results are made available for other purposes and to share with regional partners. The CBW-cont-stream-temp-Data product demonstrates the efficient QAQC review of continuous stream temperature data from multiple sources, with this example focusing on temperature monitoring to facilitate the development of regional stream temperature models that can evaluate mitigation potential of forested riparian zones in the mid-Atlantic.
Description:
This subproduct includes the input data and output data (i.e., results) of EPA's CBW-cont-stream-temp-QC program (ACE.409.4.2.8). These datasets and the accompanying readme file are stored separately on Zenodo (https://zenodo.org/records/15547233). The input data includes multiple sources of continuous stream temperature monitoring data and monitoring station information for the Chesapeake Bay Watershed. By applying the CBW-cont-stream-temp-QC program with the full input data, users have the ability to reproduce the QC-aggregated results in the output data, providing method and data-transparency. The output datasets include QC-aggregated site information, summarized daily temperature data, and summarized monthly temperature data that were developed for spatial stream network (SNN) regional temperature modeling with the NHDPlusHR flowline network. The user has the ability to use the QC-aggregated temperature data and site information for their own purposes. This data product facilitates future development of regional stream temperature models that are needed by EPA and its regional partners in the mid-Atlantic to evaluate mitigation potential of forested riparian zones in order to protect cold-water stream habitat.
