• Abstract:
  The use of Virginia's tributaries of the lower Potomac River (downstream of Great Falls) ; by striped bass, American shad, hickory shad, and river herring (a collective term for alewife ; and blueback herring) was determined by reviewing literature, consulting knowledgeable ; agency personnel, and interviewing local fishermen and landowners. Barriers to upstream ; movement were identified for each tributary, and all highway crossings were evaluated for ; their impact on spawning migrations. ; A total of 148 tributaries in the lower Potomac River downstream of Great Falls were ; identified from topographic maps as potential spawning streams. Of these, 40 are confirmed ; as spawning streams, 83 are deemed probable spawning streams, and 25 are unlikely ; candidates. Identified barriers to upstream movement on these 148 streams are as follows: ; 10 are open their entire length, 116 have natural impediments, 6 have highway crossing ; barriers, and 16 have other anthropogenic structures. Descriptions of the six highway ; crossings are presented in the text.
