Stream Health and Monitoring
Clark County provides watershed management to protect our water resources, including lakes, rivers, streams and wetlands. Monitoring provides data on a watershed’s overall health, as well as the health of individual streams within the watershed.
Monitoring allows the county to understand if a waterway is degraded and if its overall condition is improving, deteriorating or not changing. Staff uses the information to design improvement projects, coordinate with other agencies and partners, and develop educational materials about watershed health and what the community can do to protect its watersheds.
Types of Monitoring
Monitoring activities are conducted throughout Clark County’s watersheds, including:
- Stream flow and rainfall data
- Volunteer Monitoring Resource Center
- Watershed Assessment
Additional Water Data
The Washington Department of Ecology maintains records of water wells, decommissioned wells and resource wells. Electronic copies of well records are available at: https://fortress.wa.gov/ecy/waterresources/map/WCLSWebMap/
