Volunteers go through a two day training that prepares them to collect chemical data.
Volunteers have help from Blue Thumb staff for fish collections and macroinvertebrate collections – Northern Studfish
Habitat information is recorded when fish are collected, and to a lesser degree during the macroinvertebrate collections. Taking information on substrate, riparian area condition, amount of shade over the water, depth, instream cover, etc.
Because the OCC WQ Division’s Rotating Basin Program, we also have “High Quality Streams” against which we can measure the volunteer monitored streams.
The high quality streams are from the various ecoregions, and it is by ecoregion that the average of the HQS with the volunteer monitored streams are compared. OK is rich in ecoregions, another reason why we live in a pretty special state.

Volunteers and their Data ~ What We Know about Blue Thumb Streams
Stream Protection through Education ~ volunteers who monitor and educate the public
Blue Thumb volunteers collect information about streams. Blue Thumb is a nonpoint source education project.
Focus of presentation is streams.
Chemical monitoring and site observations
Fish collections Macroinvertebrate collections
Habitat Information
These different pieces of information fit together to give a good picture of a stream.
Volunteers gather data over months and years. The stream data is meaningful.
Stream data becomes MORE meaningful when you have a dependable comparison.
High quality streams have been designated for all Oklahoma ecoregions. High Quality Streams known to have high quality fish and macroinvertebrate populations, in-stream and riparian habitat, and water quality.
Blue Thumb staff works with volunteers to review stream data and compare it against the high quality streams.
Different fish and macroinvertebrate species have different abilities to tolerate pollution and habitat changes. How does the life in YOUR stream compare to the life in your ecoregion’s high quality streams?
Important – Volunteers can see trends, changes at their own sites.
Volunteers review data they have gathered and work with staff to produce reports.
Use information to educate citizens about local streams.
People want to know about local stream health. People can protect streams.

Some streams need help… some streams are wonderlands of life.

Fish Collection
We keep at least one specimen of all species in a jug of formalin to quality check our field identification.
Sometimes the fish are too big for the jug so we take a photo.
