Important Update: Starting 12/29/2025 access to the application will require registration through WBKey, our single sign-on (SSO) platform. This includes security enhancements such as multi-factor authentication (MFA) and simplified access to supported Water Boards applications. Once the change goes into effect you will need to re-register with the application through WBKey.
