South Fork Clearwater River Call for Data

DEQ is conducting a call for water quality data collected within the South Fork Clearwater River basin (Hydrologic Unit Code 17060305). Idaho Code §39-3611 (7) requires DEQ to review total maximum daily loads (TMDLs) every five years. Several TMDLs were previously developed within the South Fork Clearwater basin: the Cottonwood Creek TMDL and South Fork Clearwater TMDLs. DEQ seeks data collected within the South Fork Clearwater basin that may be relevant to DEQ’s review of the TMDLs. The map below and a downloadable shapefile delineate boundaries of the South Fork Clearwater basin.

Specifically, DEQ seeks:

  • Data for pollutants addressed in the TMDLs:
    • Bacteria (Escherichia coli)
    • Nitrogen (any forms)
    • Phosphorus (any forms)
    • Sediment (including total suspended solids, suspended sediment concentration, or bedload sediment data)
    • Temperature (continuous temperature logger data)
    • Dissolved oxygen
  • Stream flow data
  • Stream physical data, such as riparian condition, bank stability, stream wetted width, etc.
  • Biological assessment data (e.g., macroinvertebrate, periphyton, etc.)
  • Fisheries data, especially information about where salmonid spawning occurs within the basin
  • Geographic Information Systems (GIS) data sets with relevant land use, water quality, physical, or biological information
  • Information on restoration activities

If you submit data to DEQ, please also provide the following:

  • Location information for each data point, such as latitude, longitude, and datum, or a shapefile with sample points
  • Documentation of quality assurance and quality control procedures. Often, this information is documented in a project field sampling plan, quality assurance project plan, or report
  • Relevant metadata, such as column descriptions for data in spreadsheet format, GIS metadata, or a document with a guide to files (if many data files are submitted)

DEQ will accept any data that meet the above criteria and were generated in 2000 or later. Although data collected within the last five years are most useful, DEQ may also use older data to identify and document trends.

DEQ will evaluate the quality of submitted data following procedures outlined in Section 4.2 of DEQ’s Water Body Assessment Guidance to determine if and how DEQ will use the data.  If DEQ determines data are of sufficient quality, DEQ may use it for a variety of purposes, including in DEQ’s review of the Cottonwood Creek and South Fork Clearwater TMDLs, or in comprehensive state water quality assessments (Idaho’s Integrated Report).

DEQ has created a DEQ cloud location where data can be deposited. To submit data:

  1. Go to the DEQ cloud (https://cloud.deq.idaho.gov/s/jPWRzHydjSdFJXQ), click + to create a folder. Name the folder using your name. Create additional subfolders as needed.
  2. Drag and drop files into the relevant folder(s).
  3. Email or call Jason Williams (jason.williams@deq.idaho.gov, 208-799-4370) to notify DEQ that data have been deposited.

If data are already publicly available through data repositories such as Water Quality Portal or StreamNet, simply add a Word file with relevant information to the cloud or email Jason Williams the relevant information.  If you plan to collect data in 2018 or 2019 that meet the above criteria, please notify DEQ of your plans; DEQ may be able to coordinate its own data collection plans with yours and share data.

If you have questions prior to submitting please contact Jason Williams via e-mail or at 208-799-4370.  Thank you in advance for your help with this effort. If you have already supplied DEQ with the requested data, please disregard this inquiry.
