Water Quality Data from Piti Channel and Surrounding Waters Before, During, and After Cabras Island Power Plant Construction

This data package was created 2025-12-03 07:08:45 by NPSTORET and includes selected project, location, and result data. The water quality are from 7 reports documenting the effects of the construction and operation of the Cabras Island Power Plant and operation of the Piti Power Plant on Piti Channel and surrounding waters from 1972-1977.

Data contained in WAPA_NPSTORET_BE.ACCDB (NPSTORET back-end file) were filtered to include:

Organization:
- WAPA: War in the Pacific National Historical Park
Project:
- WAPA0001: Piti Channel and Surrounding Waters Before, During, and After Cabras Island Power Plant Construction
Station:
- Include Trip QC And All Station Visit Results
Value Status:
- Accepted or Certified (exported as Final) or Final

The data package is organized into six data tables:
- Projects.csv - describes the purpose and background of the monitoring efforts
- Locations.csv - documents the attributes of the monitoring locations/stations
- Results.csv - contains the field measurements, observations, and/or lab analyses for each sample/event/data grouping
- HUC.csv - enumerates the domain of allowed values for 8-digit and 12-digit hydrologic unit codes utilized by the Locations data table
- Characteristics.csv - enumerates the domain of characteristics available in NPSTORET to identify what was sampled, measured or observed in Results
- Taxon.csv - enumerates the domain of taxa available in NPSTORET to identify the organism sampled for Results

Period of record for filtered data is 1972-01-01 to 1977-11-14. This data package is a snapshot in time of one National Park Service project. The most current data for this project, which may be more or less extensive than that in this data package, can be found on the Water Quality Portal at:
