River Management Society, 9th Biennial Conference

Portland, Maine
May 15th 2008
For: River Management Society
Presented By: Eva Walker

Parish Geomorphic’s Eva Walker presented a case study entitled “Restoration of Ridge Brook, Canadian River Watershed, New Brunswick: a Restoration Success Story in the Making”, to provided a comparison of fish population surveys before and after construction, as well as to discuss some of the major project outcomes. The restoration of a section of Ridge Brook, New Brunswick was undertaken by Parish Geomorphic for a local watershed group to improve fish habitat, in particular that of Atlantic salmon. Often pre-restoration measures of fish populations are not undertaken for these types of projects. The restoration of Ridge Brook is an exception to this rule. Population assessment had occurred at a degraded section of the brook for several years’ pre restoration and yielded 3- 4 species in low numbers. Post restoration 11 species were found in overwhelming numbers. This success not only confirmed the value or habitat restorations, but has raised interesting questions about the re-colonizing community post-restoration.
