creek health

Two volunteers wear waders and dark red plaid shirts. The one on the left holds an algae-covered rock that is about 12 inches long. The volunteer on the right uses a red ruler to measure the width of the rock. The data that they collect will be used to calculate the overall bioassessment survey results for the year.

Bioassessment Survey Results 2019: Tracking the Health of Local Creeks

Jul 17, 2020

While pressure transducers and other automated equipment collect important data, much of our long-term dataset is collected by hand. Volunteers measure water quality each month by going out to creek or bay sites with equipment in hand. They take note of things like water temperature, dissolved oxygen content, and other measures that indicate creek health.
