Contents Notes |
The Oregon Streamflow Duration Assessment Method is a scientific tool developed by the U.S. Army Corps of Engineers (Corps) and the EPA to help identify waters that may be subject to those agencies' regulatory jurisdiction. The method is a major step in evaluating streams and ensuring environmental protection of water resources. The Oregon Streamflow Duration Assessment Method provides a process for quickly analyzing over 20 environmental factors in the field, and is used to distinguish between ephemeral, intermittent and perennial streams. The information helps determine whether a stream may be subject to jurisdiction under Section 404 of the Clean Water Act. In Oregon, many projects that require a Section 404 permit also require an Oregon Department of State Lands permit under Oregon's Removal-Fill Law, and there is a joint permit application process. |
