Description

Abstract: The 2011 Rapid Bio-Assessment inventory of the Luckiamute Watershed was a replicate inventory that attempted to target the most productive salmonid habitats in the basin. This was the fourth consecutive inventory in the basin designed to describe the distribution and relative abundance of coho, cutthroat trout and winter steelhead. The entire basin (214 stream miles) was inventoried in 2008 utilizing the RBA protocol which included many miles of dysfunctional aquatic habitats that currently exhibit deep channel entrenchment, elevated summer temperature profiles and provided limited summer production potential. Survey efforts were reduced to 96.6 stream miles in 2009 and covered only the highest quality habitat reaches. Surveys were further refined in 2010 to a subset of the highest quality habitats (90.2 stream miles) and reduced again in 2011 to 84.6 stream miles. Some streams in the basin were also surveyed in 2002 and 2003 in a separate effort funded by Boise Cascade, the previous owner of the current Forest Capital holdings. These included Beaver, Boulder, Clayton, Cougar, Miller, Pedee, Ritner, Sheythe, West Fork Luckiamute, Wolf, and approximately 7 miles of the upper Luckiamute mainstem. Results and comparisons to those surveys are included below in the Site Specific observations. The intent of the RBA inventory was to gather information on the status of juvenile salmonid summer distributions and summer rearing densities. The inventory consisted of extensive snorkel surveys that began at the mouth of each stream and continued to the end of significant salmonid rearing potential (not to the end of cutthroat distribution). These surveys will be used to develop a base line for understanding how juvenile salmonids are currently utilizing habitats within the basin during summer flow regimes. Replicates of this inventory in high priority stream reaches (streams exhibiting residual system function) will be critical for identifying trends in the distribution and abundance of juvenile coho, steelhead and cutthroat in response to watershed restoration and management. The Rapid Bio-Assessment (RBA) survey method was designed to sub-sample 20 percent of the pool habitats using a Rapid Assay technique that could cover large distances and succeed in describing the current distribution of juvenile salmonids in all of the surveyed streams and their tributaries. Beaver dam frequency was also recorded.
