| Abstract/Description or Keywords | In October 2007 BC Parks completed a Level 1 Impact Assessment Report concerning previous year flood damage to streamside trails in the lower reach of the Goldstream River (Neufeld & Associates). This assessment highlighted the need for hydrologic and geomorphological assessment to guide future remediation and trail work resulting in this preliminary review. The field assessment by Neufeld and Associates identified the following kinds of problems: • flooding and loss of trail surface • stream bank instability • trail encroachment within the active stream channel • trail drainage and cross trail erosion • inadequate rip rap design and impacts on stream channel widening and migration • log jam impacts • pedestrian bridge location and abutment scour • loss of riparian function ( foot traffic and vegetation clearing) The purpose of this report is to bring together what is known about the hydrology and stream morphology into a brief summary. Extensive stream attribute data was collected in stream surveys by LGL Ltd. in 1998 and 1999 as a basis for identifying fish habitat restoration opportunities and to develop prescriptions. While most of the field data information is now 10 years old, it provides a starting point for interpreting more recent changes in the watershed. Much of the data remains relevant and can be leveraged for use in current planning. This report provides additional interpretation and analysis of selected stream attribute data in these reports together with analysis of available hydrometric records. This information was supplemented by field observations in February 2008. However, no new survey data has been collected. Additional field surveys are required to account for changes that have occurred and to meet design needs. The original documents listed below should be read for a complete background.
