The purpose of this site is to help people learn how to identify the class of various primary headwater streams through a headwater habitat evaluation index ( HHEI ). The HHEI process includes three different matrices: substrate, pool depth, and bankfull width. The good thing about someone learning how to use the HHEI method, is that it's easy, fast, and doesn't require any special skills.
