We understand how important it is to provide you with a safe and reliable water supply. That's why we created a broad-based, water-quality monitoring program to measure the health of the McKenzie River. We're always looking for possible threats to our community's drinking water. We are very fortunate that the McKenzie River has excellent water quality, and we do our best to keep it that way.
We collect water samples from sites along the McKenzie River and its tributaries to measure current water quality and compare them to past samples to find out if water quality is changing over time. We also check the water for pesticides, metals, nutrients and bacteria that can wash into the river during storms. In summer months, we check reservoirs in the McKenzie Watershed for harmful algal blooms (HABs).
Algae blooms and cyanotoxins
We monitor the McKenzie Watershed for cyanobacterial harmful algal blooms (cyanoHABs) throughout the spring and summer to make sure your drinking water is safe. When we spot a bloom in Cougar Reservoir or Blue River Reservoir, we immediately begin sampling for cyanotoxins.

Drinking water quality
Even with a high-quality source like the McKenzie River, we still have to filter and disinfect the river water to deliver safe drinking water to your home or business. At our Hayden Bridge filtration plant, we work hard to deliver water that meets or exceeds all state and federal health standards so that you can enjoy tasty and healthy drinking water right from your tap. We use a three step process to turn water from the McKenzie River into safe drinking water and our technicians, as well as independent laboratories, collect and test more than 85,000 samples from source to tap each year.Learn more
