Water temperature is an important characteristic of stream conditions with implications for water quality and stream dwelling organisms. This Data Release contains spatial stream network (SSN) objects and R scripts to run SSN models to predict mean monthly stream temperature and 7-day average daily maximum (Max7DAD) during August and September in the White River watershed within Mount Rainier National Park, Washington. Monthly predictions for August and September are derived and calibrated from stream temperature data collected by the National Park Service between 2010 and 2020 within the White River and its tributaries. These predictions are average conditions that correspond to the timeframe 2010 - 2020. Functions...

This dataset presents paired air and stream temperature measurements from 11 sites in the Olympic Experimental State Forest within the Quillayute River Basin, Washington, and metrics to understand groundwater influence and thermal sensitivity at these sites. The study area consisted of upper reaches of the Dickey, Calawah, Sol Duc, Bogachiel Rivers, above their respective confluences with the Quillayute River. Paired, or co-located, air and stream water temperature data were collected continuously (every 60 or 120 minutes) by the Washington State Department of Natural Resources (WADNR), Forest Resources Division, between 2017 and 2022 (Minkova and Foster, 2017). Stream water temperature data were screened by WADNR...

This Data Release contains supporting data to evaluate fine sediment infiltration into gravels in identified locations of Chinook spawning habitat at three sites on the Sauk River, located in western Washington. Fine sediment infiltration into the river substrate that salmonid fish species use to spawn has been shown to increase mortality during the incubation and pre-emergence phase when salmonids are still residing in the subsurface gravels. The contents of this data release include; 1) geographic coordinates for the three site locations along the Sauk River, 2) hourly dissolved oxygen concentration in the subsurface at the three site locations, and 3) grainsizes, defined as fraction finer than a given sieve size...

The Quillayute River Basin in northwestern Washington consists of the Quillayute River and the river systems of its major tributaries, the Dickey, Sol Duc, and Bogachiel Rivers. With a drainage area of 629 square miles, the Quillayute River Basin provides important habitat for 23 distinct runs of anadromous steelhead and salmon, representing one of the largest and most productive watersheds on the Washington coast (Nelson, 1982; Hunter, 2006). The Quileute Tribe maintains treaty-protected fisheries at usual and accustomed areas in the Quillayute River Basin; however, these fisheries are currently at risk during the late summer as water temperatures within these areas may exceed the specific thermal tolerances of...

This dataset provides a zipfile containing 20 shapefiles with geo-referenced longitudinal stream temperature profiles (LTPs; .shp). Profiles were obtained from longitudinal “Lagrangian” drag-probe temperature surveys ("float surveys") of the Quillayute River, Washington. Near-streambed and near-surface water temperature and conductivity were measured at three-second intervals using HOBO U24 sensors and the spatial location of each measurement was recorded using a GPS while drifting downstream in a kayak at ambient stream velocity following the method of Vaccaro and Maloy (2006). The study area consisted of the Quillayute River from its upstream-most point at the confluence of the Sol Duc and Bogachiel Rivers to...
