Water quality

Turbidity, dissolved oxygen, temperature.

What's in the water

Flow tells you how much; quality tells you what. Turbidity, dissolved oxygen, temperature, and a few ions — read from sensors we put in the river, and from grab samples we still take by hand.

What we track

turbidity  sediment, in NTU
DO         dissolved oxygen, mg/L
temp       hourly, year-round
grab       lab samples for nutrients + metals

Why it matters

A river can be full and still be dead. Quality is the difference between water and habitat.
