Self-calibrating Palmer Drought Severity Index values averaged per water year with associated streamflow permanence data products for the HUC17 Pacific Northwest Region
February 12, 2025
This data release includes estimated Self-Calibrated Palmer Drought Severity Index (scPDSI) values and ancillary information for three data products that had previously been developed for the Pacific Northwest Region (HUC 17).
The data products are stored in three child items:
1. National Hydrography Dataset High Resolution Flowlines: This child item contains the flowlines in the National Hydrography Dataset High Resolution (NHDPlus_HR, 1946-1999). Files include flowlines within the 12 HUC4 boundaries for the study area (1701-1712).
2. Self-Calibrating Palmer Drought Severity Index Values: This child items contains the self-calibrating Palmer Drought Severity Index Values for raster pixels that correspond to the Probability of Streamflow Permanence (PROSPER) Model Output Layers for the Pacific Northwest region (version 2.1, 2004-2016) and which also corresponds to the NHD Medium Resolution streamgrid (flow accumulation grid threshold of 100 pixels).
3. Results from the FLOw PERmanence (FLOwPER) Application: This child item contains the flow/no flow field observations (2019-2023) collected using the FLOw PERmanence (FLOwPER) feature mapping application. These observations were not used to train the PROSPER model; observation locations that have not been georeferenced (snapped) to NHDPlus_HR flowlines or NHD Medium Resolution streamgrid.

Streamflow Permanence in the Pacific Northwest
Not all rivers and streams flow year-round. Understanding when and where streams flow or go dry is critical for managing land use, water quality, and water availability on landscapes. The USGS and partners are studying streamflow permanence in the Pacific Northwest. We are gathering data, developing new models, and providing data visualization and outreach tools.
