Baseline Stream Monitoring

Five volunteers in a stream on a cloudy day standing in a circle. One volunteer in the middle is holding a tray filled with water and macroinvertebrates. the other four volunteers look on.

Baseline volunteers visit the same stream site once a month from May to October to gather baseline information about the health and water quality of the stream. With multiple years of consistent baseline data, we can better detect changes to the stream’s water quality from land use changes or restoration efforts.

What is Measured

The goal is to assess six elements of stream health using scientific tools and techniques:

  1. Dissolved oxygen – aquatic life depends on it.
  2. Water temperature – affects oxygen demand
    and can limit creatures’ survival.
  3. Transparency – too many suspended particles
    in the water can be harmful to aquatic plants
    and other organisms.
  4. Streamflow – the amount of flowing water in
    a stream is an important habitat limitation.
  5. Stream macroinvertebrates – insects, worms,
    crustaceans, clams and other small, boneless
    creatures that are visible without the aid of a
    microscope are used to assess water quality
    based on their tolerance to conditions.
  6. Aquatic invasive species – introduced organisms
    can cause economic or environmental harm
    and disrupt the aquatic food web.

All Water Action Volunteers data is entered into the Wisconsin Department of Natural Resources (DNR) Surface Water Integrated Monitoring System (SWIMS) database. The SWIMS database is used by DNR staff to enter and search for water quality monitoring information for assessing the health of our state’s waters and to guide water protection and restoration decision-making. The database is also linked directly to the DNR’s Surface Water Data Viewer online mapping tool.

Datasheets

Use this datasheet for all Baseline Monitoring parameters and some Special Projects Monitoring parameters. Print your datasheet to take to the stream or fill out the datasheet on a digital device (just remember to download and save the file first!).

Be on the lookout for four key aquatic invasive species while conducting your stream monitoring, to help prevent the spread of these organisms in Wisconsin. If you suspect you’ve found an aquatic invasive species, follow the steps in this factsheet to identify, document and report your find!

Interested in understanding the math behind WAV’s streamflow float method? Calculate streamflow by hand using this worksheet! Remember that the float method consistently overestimates streamflow by 24%, so you will need to account for this difference if you use the worksheet.
