Water Quality Monitoring Program

Water quality monitoring is an important aspect of City of Bothell's surface water program. The City currently conducts two types of monitoring:

• Fecal coliform bacteria monitoring for North and Swamp Creek
• Long-term habitat and living organisms monitoring for local streams

What do we monitor for?

We typically monitor for fecal coliform, E. coli, bacteria, pH, dissolved oxygen, temperature, stream flows, nitrate/total nitrogen, phosphate, and benthic macroinvertebrates.
