castroRestoration Innovation – the next big thing
Friday, January 12th, 12 pm CST
Speaker: Janine Castro, Geomorphologist, US Fish and Wildlife Service
Watch the recording.

Channel relocation and reconstruction have become common place, perhaps even a bit pedestrian, in Pacific Northwest stream restoration.  In the past, we often strove to increase available aquatic habitat by lengthening a channel, decreasing the spacing between pools, changing the channel width, or adding large wood. As a stream restoration community, we were historically very “channel-centric” with much of our design time dedicated to calculating the perfect channel size – not too big, not too small, but just right. Our goal was to create the ideal transport channel to pass water, sediment, organics, and species while neither appreciably aggrading nor degrading. We dialed in the stream slope, cross-sectional area, and roughness to achieve a state of perceived channel bliss. When the newly minted channel “adjusted” during high flow events, and those changes were not anticipated, we scratched our heads and wondered which parameter we got wrong.

Nowadays, we are more likely to work not only in the channel, but on the floodplain as well. We’ve raised stream beds, added side channels, alcoves, seasonally inundated wetlands, and large wood to floodplains as well as channels, thus recognizing that a stream system functions over a whole host of flows and that flow diversity often improves biodiversity.  Yet we still struggle to determine if we should construct one, two, three, or, even more revolutionary, perhaps no channels?

This talk will cover where we’ve been, where we are, and where we might be going with stream restoration in the Pacific Northwest.

Hatcathanasakeshery Creek Stream Restoration Project - A Unique Opportunity to Maximize Trout Habitat, Create Recreational Opportunities and Provide Mitigation Credits
Friday, May 5th, 2017 12:00 pm (Central Time)
Speaker: George Athanasakes, Ecosystem Restoration Services Leader, Stantec
Watch the recording of this seminar.

Abstract: The Hatchery Creek Stream Restoration project is a unique opportunity to utilize the latest stream restoration techniques to maximize trout habitat, create recreational opportunities, and provide mitigation credits.  The project is located immediately downstream of the Wolf Creek Dam US Fish & Wildlife National Trout Hatchery near Lake Cumberland in Jamestown, Kentucky.  The project was constructed in 2015 and extended an existing 400 foot long channel, which is the outflow from the trout hatchery to create approximately 6,000 feet of trout stream habitat.  In an effort to maximize habitat and recreational opportunities, the project was designed to provide a variety of habitat for all life stages of trout and included a variety of stream types including A, C and DA channels.  This project has several unique aspects, which are not typical to stream restoration projects, including a constant flow of approximately 35 cfs, which is approximately 70% of the upstream bankfull flow, limited sediment supply, and the need to maintain imported spawning gravels.  

This talk will focus on the design and implementation of this project under a design/build project format.  In particular the development of the habitat features will be discussed in detail including the stream type and habitat type selection process and how the different stream types and habitat features relate to the various trout life stages.  In order to maximize the habitat and recreational features the design team included aquatic biologists as well as avid fishermen.  In addition, input from key project stakeholders was sought throughout the design process including through a two-day QAQC meeting.  Project implementation will also be discussed including the coordination with numerous stakeholders, project staging, and construction methods utilized.

Flows were released into the channel in November, 2015 and the project is currently being monitored to confirm usage for the various life stages of trout including spawning.  The project also included an artificial upwelling device to help minimize settling out of fines and to promote upwelling in the newly constructed stream.  This talk will also describe the techniques being utilized to monitor the site, which includes a review of the site to confirm the presence of redds, macroinvertebrate sampling, collection of wood loading data, fish shocking/sampling, and the use of snorkeling surveys to confirm habitat usage.  Results of the monitoring to date will also be presented.

Speaker: Peter Wilcock, Department of Watershed Sciences, Utah State University
Ohio PRRSUM Showcase, Watershed Stewardship Center, Parma, Ohio
 
Biography: Prof. Wilcock received his PhD in Earth Science at MIT in 1987and specializes in erosion and sedimentation processes and their application to watershed restoration and management.  After serving on the faculty of Johns Hopkins University for 27 years, in 2014 he joined Utah State University as Head of the Watershed Sciences Department in the Quinney College of Natural Resources. Prof. Wilcock is a Fellow of the American Geophysical Union and received the Hans Albert Einstein Award from the American Society of Civil Engineers for outstanding contributions to the understanding of sediment transport in gravel-bed rivers. Prof. Wilcock endeavors to understand the movement of sediment from the scale of grains to the watershed and to use this understanding to guide public decisions regarding stream restoration, water quality, and watershed management.

Hans TriticoNow that's a beautiful stream...are there any fish? Habitat Restoration and the Role of Perception 
Wednesday, April 1st (4.1.15), 12:00 pm (Central Time) 
Hans Tritico, University of Mount Union

Abstract: Restoration projects are undertaken for a wide variety of reasons. One commonly stated reason is to improve fish habitat. This presentation will briefly review what is currently known about fish habitat selection and compare that body of knowledge to our current design practices. What we find through this comparison is that while fish choose habitat based on their unique perception of the environment, we tend to restore streams based on our own perception of their environment. One prescient example of how a fish’s perspective of its environment is dramatically different than our own is the existence of the lateral line system in most fish species. The lateral line system detects near field vibrations in the water. This system is used in a number of behaviors including orientation, positioning, and predator-prey interactions. It is also apparent that in a number of low visibility environments that the lateral line system is the primary way fish perceive their environment. Fish habitat in low visibility streams, which occur frequently across the Midwest, is therefore more strongly connected to the temporal flow conditions than to the visual layout of an aquatic environment. The existence of two distinct lenses (fish perception vs. human perception) means that stream restoration projects which include a stated goal of restoring fish habitat may increase their efficacy by working to align the two perspectives. To this end a number of researchers have been working to design instruments that will let us better understand the spatial and temporal flow variations as fish experience them. While changing perspectives may eventually mean some adjustments to our current design practices it also provides a new framework for achieving increased habitat restoration in agricultural and urbanized environments.
