Air temperature, water temperature, and specific conductance of water were continuously measured with data loggers (measurement interval = 30 min.) from 2014 to 2024 at six wadeable stream sites throughout Delaware Water Gap National Recreation Area (n = 3) and New River Gorge National Park and Preserve (n = 3). Data loggers were deployed at stream reaches where benthic macroinvertebrate, fish, and streamside bird communities have been monitored by the National Park Service since 2014. These data were collected as part of a multi-agency Regional Monitoring Network of reference (i.e., relatively undisturbed) streams throughout the Mid-Atlantic Region. Sites were selected based on their high degree of ecological integrity as inferred from previous biological surveys. Methods followed existing protocols that were consistent with approaches used throughout the Regional Monitoring Network.

Continuous water temperature measurements were recorded at 59 locations in wadeable streams (watershed size = 2 - 100 km2) throughout Delaware Water Gap National Recreation Area and New River Gorge National Park and Preserve from April 2022 to November 2024. Data loggers were deployed at probabilistically selected sites where benthic macroinvertebrate, fish, and streamside bird communities have been monitored by the Eastern Rivers and Mountains Network (National Park Service) since 2014.

The Northeast Temperate Network (NETN) monitors water quality and water quantity at 9 national park sites to document the status and trends of their lake, pond, and stream resources. NPS scientists have collected standardized measurements of stream discharge, stream and lake stage, water transparency, in situ water quality (temperature, dissolved oxygen, pH, etc), and other measurements from May to October every year beginning in 2006. Water samples were also collected each year to measure nitrogen and phosphorus to assess potential nutrient enrichment. This data package contains a cumulative record of all water monitoring data collected at NPS IMD NETN park units through the most recent field season and is organized into twelve (12) datasets: Chemistry_Data_Long_YYYYMMDD.csv – water sample chemistry and nutrient data (e.g., TN, TP, ANC, Chl-a). Long format. Chemistry_Data_Wide_YYYYMMDD.csv – water sample chemistry and nutrient data (e.g., TN, TP, ANC, Chl-a). Wide format. Discharge_Data_YYYYMMDD.csv – stream flow data collected by a current meter. Event_Info_YYYYMMDD.csv – sampling event-level data (e.g., date, observer, meteorological conditions, etc.) Light_Penetration_Data_YYYYMMDD.csv – profiles of photosynthetically active radiation collected by a light meter. Secchi_Data_YYYYMMDD.csv – Secchi disk depth data. Sites_Lake_YYYYMMDD.csv – precise location data and descriptive information for NETN lake sites. Sites_Stream_YYYYMMDD.csv – precise location data and descriptive information for NETN stream sites. Sonde_InSitu_Data_YYYYMMDD.csv – profiles of in situ multiparameter sonde measurement data (e.g., specific conductance, pH, DO, etc.). StageDatum_Info_YYYYMMDD.csv – information on water level benchmarks (e.g., elevation, datum type, etc.). StreamSite_Observations_YYYYMMDD.csv – specific observations about water appearance (e.g., color, algae type, etc.). WaterLevel_Data_YYYYMMDD.csv – water surface heights relative to established benchmarks, including partial and continuous gage station elevation records.

USGS collects streamflow, dissolved oxygen, pH, specific conductance, and water temperature for the Northern Great Plains Network on a 3 year rotation during the ice free season. Provisional data can be accessed from the NWIS external link for 2013, 2016, and 2019. Data for 2019 are attached.

This database contains hourly water and air temperature data from 120 site locations within 17 watersheds in Shenandoah National Park, Virginia between June 23,2012 and October 25, 2016. The database includes three separate table files (i.e, entities) in csv format: 1) Water temperature data, 2) air temperature data, and 3) site location data. All temperature data were collected using HOBO Pro V2 thermographs (accuracy = 0.2 degrees Celsius, drift = <0.1 degrees Celsius per year per year). These raw data were summarized to mean daily air and water temperatures for the analysis used in Johnson et al. (cited above).

The data were collected summer, 2016, 2017, and 2018. Continuous temperature loggers were deployed along the Pend Oreille River between Albeni Falls Dam and the Box Canyon Dam. Loggers were checked every 1-2 weeks throughout the summer.

This Data Release contains stream temperature observations for 28 sites in the Antietam Creek Watershed (Maryland) during summer 2021. Data were collected using Onset ProV2 temperature gages within perforated PVC cases attached to stream substrates with rebar. Temperature gages were deployed and retrieved by volunteers with the Antietam-Conococheague Watershed Alliance. Temperature records are provided for 20-minute increments between June 1 and August 31, 2021 (92 days, 6625 observations per site, and a total of 185,500 observations in the dataset). Site location coordinates are provided.
