The creeks, lakes, and scenic views of waterways in Kirkland help make it a great place to live, work, and play. Clean water and healthy habitat is essential to the quality of life for the people and wildlife that call Kirkland home.
Kirkland monitors the health of 12 watersheds using physical, chemical, and biological data. We can use this data to identify issues and learn where actions are making a difference. These dashboards share the results of these monitoring efforts.

These annual report cards show the health of Kirkland creeks based on a 1-100 score on the Water Quality Index. You can think of these scores like grades on a test: 90-100 is an A, 80-90 is a B, and so on. Look closely at the water quality scores: watersheds may score high on some metrics, but score poorly on others. Low scores in one area may indicate that nearby human activity is negatively affecting water quality - which also means that our collective choices can help improve it.
The conditions of a watershed are dynamic and can change at any time. The information in these pages should only be used for general reference.
