Surf Your Watershed

Surf Your Watershed (SYW) has provided simple access to a rich collection of watershed information since its release more than 20 years ago. SYW has recently been decommissioned because of technology migration and related security issues.

Surf Your Watershed has been replaced by  How’s My Waterway, Version 2, which incorporates much of SYW's content and expands relevant watershed information.
