WoodiebrookLocation: Geauga County, Ohio. View location map Overview of the Problem Woodiebrook was one of Ohio's few streams that supported reproducing native brook trout populations. Development of the watershed, more specifically the impoundment of one tributary and channelization of the mainstem, adversely impacted flow volumes and water temperatures. The activities associated with constructing the dam, levees and lake disturbed the site, resulting in downstream braiding of the mainstem. As a result of these impacts, instream habitat and riparian values were lost and Woodiebrook was no longer able to support this rare and important fishery. Restoration Solution The approach taken to restore
Woodiebrook combined holistic ecosystem restoration and adaptive management.
This approach involved the disciplines of biology, geology, fluvial
morphology and engineering. The process began by utilizing historic
aerial photos, several reference reaches, and empirical data as guides
to channel location, dimension and pattern. The levees and dam were
removed and the valley and stream channels were restored to pre-disturbance
pattern, profile and dimension. More than 3200 lf of E type channels
were constructed with short sections of B-type channels used as stilling
basins immediately downstream of the road culverts. Riffles, pools
and undercut banks were constructed, the riffles constructed using
substrate native to the area. The design recognized and incorporated
fishery habitat requirements such as interstitial and groundwater
flows, depth and flow heterogeneity, undercut banks, riparian plantings
and overhanging vegetation. Construction of these details provided
the necessary habitat to re-introduce and immediately support the
trout fishery.
