IMPORTANT NOTE: More recent versions of these data release are available at this link. This dataset includes spatial locations where streamflow permanence observations (continuous flow, discontinuous flow, and dry) were recorded using the FLOwPER (FLOw PERmanence) field survey available in the Survey 123 and S1 mobile application. Additional information to describe the field conditions are included as part of the survey. Field observations in the FLOwPER Database have not been processed for quality control including spatial data accuracy or association with a stream network such as the National Hydrography Dataset. Streamflow permanence observations are collected from several governmental and non-governmental organizations...

This produced dataset includes spatially aggregated records of measurements and observations from public and private organizations across the Upper Missouri River Basin. For this dataset the Upper Missouri River Basin is defined as Hydrologic Unit Code 1002-1013, and includes the states of Montana, Wyoming, Utah, North Dakota, and South Dakota. Streamflow measurements are an essential part of understanding the relationship between streamflow permanence and climatic and physical factors. For the purpose of this investigation, all streamflow observations were identified as perennial, non-perennial, or pooled to be used in the PROSPER (PRObability of Streamflow PERmanence) model.
The HIP community is a collaboration of scientists in the Pacific Northwest focused on advancing a holistic understanding of intermittency in headwater areas. The goal of this specific project is to gather previously collected streamflow permanence data from efforts throughout the Pacific Northwest and use those data to develop models to predict where streams might go dry under current and future climate conditions. Additionally, the models will be used to improve land managers’ ability to identify ecologically-significant headwater streams resilient to drought conditions enabling them to focus their limited rehabilitation and conservation resources on watersheds necessary to support populations of threatened aquatic...

This dataset includes hourly stream and air temperature data from 124 sites throughout the Northern Great Basin region of SE Oregon. Data loggers were deployed June through September of 2016 and downloaded each subsequent summer through 2019. The spatial data layer contains site locations, geographic information, data summaries, mean August stream temperatures, and modeled NorWest stream temperatures. The Wet-Dry delineation file contains daily flow status estimates derived from stream temperature data for each site. The Site Visit file contains the date and time of the site visit along with associated information on site flow conditions, water depths, logger conditions, and stream logger water depths.
