Description
Streams are linear ecosystem highly constrained in two dimensions. Movement of organisms and abioticcomponents such as sediment and woody debris is highlyone-dimensional (upstream/downstream) and vulnerable to fragmentation. Undersized culverts present a majoranthropogenic barrier to fish passage and are a primarycontributor to breaks in watershed process continuity.Project SHARE has been actively engaged in on-the-ground habitat enhancement projects in the Down eastAtlantic Salmon watersheds. Since 2004, SHARE has restored stream connectivity at over 100 road/stream crossings using the principles of “Stream Simulation Design”.
The presentation will highlight symptoms of altered stream process and barriers to fish passage by traditionalundersized round culverts and tools for assessingroad/stream crossings. Components of stream simulation design will be presented in detail. Photos of actual construction sites ·will document critical steps in theconstruction process including: water control, footingtypes and pipe installation. In addition, photos followinga 50 100 year rain event in December 2010 will demonstrate the concept of 1.2Xbankfull “in action”

Comments
Steven Koenig is Executive Director of Project SHARE, a Maine NGO. He received a BS in cellular biology from the University of Michigan and has graduate studies in limnology (University of Wisconsin) and fish physiology(West Virginia University). Over the past 10 years he has been actively engaged in salmonid habitat restoration in Maine. In 2009 the National Fish Habitat Action Planrecognized Mr. Koenig ·with its first national award "for
Extraordinary Action in Supporting Fish Habitat Conservation." The West Branch of the Machias Riverwas named a one of NFHAPs "10 Waters to Watch" in 2010.
