Description

Abstract: This project applied standard monitoring methods to measure the results of an in-stream restoration project. The site is at the confluence of the North and South Scappoose Creeks, where the Council installed six large wood structures to provide long-term channel roughness and encourage additional recruitment of large wood. Monitoring methods included creek and vegetation cross-sections, photo points, and creek profiles. The original project called for monitoring to occur prior to construction in 2011, within the first year following construction, at year three, and at year five. The first two of these occurred as scheduled, however, due to both the dynamic site conditions, and Council staff turnover, it was determined the monitoring activities should be suspended after year three (early 2015). Project results are mixed; a significant amount of information was gathered, but follow up was difficult due to the nature of the site and staff turnover. Photo points clearly show results, but final metrics on vegetation and pooling was unable to be attained.
