Continuous water temperature data were collected at multiple sites along the Middle Fork and mainstem Willamette Rivers between Jasper and Newberg, Oregon, to support effectiveness monitoring for a large-scale channel and floodplain restoration program (Willamette Focused Investment Partnership, WFIP). Continuous water temperature loggers were deployed at a subset of WFIP restoration sites where river restoration activities were implemented to improve habitat conditions for native fish species. Data from water temperature monitoring will be used to evaluate the effectiveness of restoration activities at improving habitat conditions for Endangered Species Act (ESA)-listed salmonids and other native fish in the Willamette River. Additionally, water temperature monitoring in summer and early fall months at restoration sites is useful for determining whether thermal conditions at these sites are optimal, sub-optimal, or lethal for cold-water adapted fish species like spring Chinook salmon (Oncorhynchus tshawytscha). Water temperature monitoring for this study spans 2019 through 2022. Water temperature loggers were suspended in the water column on a wire between a concrete block and a buoy as part of a monitoring arrays installed at multiple off-channel location throughout the study area. This document describes data collected at the Bowers Rock State Park monitoring site between 08/14/2020 and 10/19/2021 and associated data quality files. The monitoring site is within a former gravel pit adjacent to the Willamette River and included various configurations of monitoring arrays consisting of water temperature loggers suspended at different elevations in the water column. Two monitoring arrays consisting of two water temperature loggers per array were deployed from 08/14/2020 to 04/15/2021, one in the southeast area of the pond and one in the northeast area of the pond. One monitoring array consisting of two water temperature loggers in the southeast area of the pond and one monitoring array consisting of one water temperature loggers in the northeast area of the pond were deployed from 04/15/2021 to 07/19/2021. Two monitoring arrays consisting of two water temperature loggers per array were deployed from 07/19/2021 to 10/19/2021, one in the southeast area of the pond and one in the northeast area of the pond. These data and metadata have been added to the data release originally published in 2021.

This document describes data collected at the Willamette Mission State Park monitoring site between 09/22/2020 and 10/18/2021 and associated data quality files. The monitoring sites are within Mission Lake, a lake not connected to the Willamette River year-round, and Windsor Slough, an alcove along the Willamette River which flows around Windsor Island. These sites contain various configurations of monitoring arrays consisting of water temperature loggers suspended at different elevations in the water column. One monitoring array consisting of one water temperature logger was deployed from 09/22/2020 to 10/18/2021 at the Mission Lake monitoring site. Two monitoring arrays consisting of one water temperature loggers per array were deployed from 09/22/2020 to 04/20/2021 at the Windsor Slough monitoring site.

This dataset consists of repeat vegetation cover maps of multiple Willamette River restoration sites where restoration activities were implemented to increase the area of floodplain forests. Beginning in the early 21st century, large-scale restoration programs have been implemented along the Willamette River, Oregon, to address historical losses of floodplain habitats for native fish (Keith and others, 2022). For much of the Willamette River floodplain, direct enhancement of floodplain habitats through restoration activities is needed because the underlying hydrologic, geomorphic, and vegetation processes that historically created and sustained complex floodplain habitats have been fundamentally altered by dam construction, bank protection, large wood removal, land conversion, and other influences (for example, Hulse and others, 2002; Wallick and others, 2013). Floodplain forest vegetation cover was derived from R Random Forest classification of 2009, 2011, 2018, and 2020 aerial imagery at three large-scale floodplain planting restoration sites along the Willamette River: Harkens Lake (river kilometer [RKM] 153-154.5), Snag Boat Bend (RKM 144-147), and Luckiamute State Natural Area (RKM 108-111). The overall goals and approaches for the repeat mapping are based on a previously published effectiveness monitoring framework for Willamette River restoration activities (Keith and others, 2022). The repeat mapping datasets include GIS layers defining two classes of vegetation cover (forest and not-forest, condensed from six cover classes: forest, not-forest (agriculture), not-forest (other), water, shadow in forest, and shadow in non-forested areas). This mapping can be used to support an assessment of changes to floodplain forest vegetation cover at sites along the Willamette River floodplain where restoration activities were implemented from 2012 to 2020 to increase the area of native floodplain forest vegetation.

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.

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.
