This resource includes water quality samples collected within the Northwest Field Canal, located in Logan, UT and from stormwater outfalls that drain to the canal. These data were collected to with the purpose of developing surrogate relationships between in situ parameters and total suspended solids (TSS) and to determine spatial loading patterns in the drainage. Samples were collected manually and via an ISCO 3700 automated sampler. These samples were then analyzed for TSS), total phosphorus (TP), and total dissolved phosphorus (TDP). Methods implemented for sample collection and analysis are described within the resource.

The following is a description of the files within this resource:

NWFC_GrabSamples_Methods.pdf: This document provides supplementary info for the methods used in collecting and processing grab samples.

TSS_TP_TDP Sample Data Folder

  • TSS_TP_TDP.xlsx Excel file containing TSS, TP, and TDP concentration values and associated metadata for each grab sample taken during the suspended solids and phosphorus study in the Northwest Field Canal in Logan, UT. The file was created by following a data entry template for Version 2 of the Observations Data Model (ODM2).

GIS_Data Folder

This folder contains a shapefile with the location of the all sites where samples were collected in the Northwest Field Canal in Logan, UT.

Supplemental_Data Folder

This folder contains the raw output from the SEAL Analytical AQ2 discrete analyzer including all samples analyzed for TP and TDP. TP_TDP_SampleLog.xlsx contains TP and TDP sample concentrations as well as the lab identifier (e.g., F199, U199) for each sample. The lab identifier is also used in the raw AQ2 output files. AQ2_RawOutput folder: This subfolder contains AQ2 output for each TP and TDP sample. Each sample is identified by a unique lab identifier. That lab identifier can be connected to a sample identifier via the TP_TDP_SampleLog.xlsx file. Each output file contains raw output, calibration curves, and QA/QC results for each sample. * TSS_Calculations folder: This subfolder includes a spreadsheet that gives the calculations used to obtain TSS concentrations for each of the samples.
