dc.description Poster from 2006 Cascades student poster session.
dc.description Human land use practices have degraded hundreds of thousands of miles of water corridors in the U.S. Fortunately, there has been an increase in effort to restore many of these aquatic habitats. Currently, the Deschutes Basis Land Trust (DBLT) is proposing to reconnect a portion of Whychus creek that flows through Camp Polk Meadow to its original flood plain in an attempt to restore historic spawning habitat for salmon and steelhead. The purpose of this study was to provide baseline water quality data for the DBLT to aid in assessing the cost/benefit of various restoration approaches as well as monitoring the success of restoration efforts. Macroinvertebrate bioassessment was used to determine biological integrity of Whychus Creek prior to restorative activities. Macroinvertebrates are good indicators of water quality because they live in the stream most of their lives, are easy to collect and identify, and differ in their tolerance to environmental change. Samples were collected within Camp Polk Meadow, upstream (control), and downstream. Invertebrates were characterized using rapid bioassessment protocols. Data analysis indicating baseline water quality is pending.
