Water quality and quantity monitoring data package for measurements collected within national parks of the Northeast Temperate Network, 2006-2024

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.
