Welcome to the interactive web schedule for the 2019 Midwest Fish & Wildlife Conference! The schedule is subject to change (as of November 7, 2018). Please check back for updates. To return to the main Conference website, go to: www.midwestfw.org.

The conference schedule is hosted in SCHED which allows you to search within the schedule, and filter the schedule to show items only occurring on a certain date or within a track/symposia.
  • To view only a certain type of presentation or track, locate the heading "Filter By Type" in the navigation bar. As an example, try clicking on "T01: Fisheries: Great Lakes I".
  • The default view for the schedule is "Simple" which only shows the start time and title of the agenda item. Hover over the button that says "Schedule" to see the different view options. The "Expanded" option will show start and end times, room location, and session description, if there is one.
  • You can build your own schedule by creating a free account with SCHED by selecting "SIGN UP." Watch the "how-to" video to learn more about using Sched. 
  • PLEASE NOTE: Adding agenda items to your schedule through this app does not sign you up for a session. If an agenda item says "pre-registration required" or charges an additional fee, you need to add the item to your registration through the online registration system

(P36) Evaluating the Fish Communities of Riffles/runs with Three Different Substrate Types in Preparation for Changes Post Lowhead Dam Removal

AUTHORS. Drew Holloway, Muncie Sanitary District Bureau of Water Quality; Kaleb Eden, Ball State University ABSTRACT. The importance of a natural flow regime has been well documented throughout the years. The traditional riffle, run, pool sequence allows a stream to optimize its community structure and allow habitat specific species an opportunity to flourish. Lowhead dams alter this process and overtime can lead to expansive impoundments reducing the amount of riffle and run habitats available. The removal of neglected and unnecessary dams will allow a stream to return to its natural state. The West Fork of White River in Muncie, In will be having two of its lowhead dams removed in the coming year allowing these habitats to return.  In preparation for these removals and the anticipated substrate changes, a 10x10m sandy run, boulder/cobble riffle and bedrock riffle were sampled using electrofishing methods. A total of 19 species were sampled for a total of 422 individuals. Five of the species were observed in all three substrate types including four Cyprinidae species. When looking at each substrate type individually we see subtle differences, like the presence of various Percidae species that were absent in the sandy run but dominant in the boulder/cobble riffle. The results of this project will be used to help explain the potential changes seen as the West Fork White River returns to its natural state.
