  • Little Butte Creek Watershed Assessment
    Little Butte Creek Watershed Assessment Little Butte Creek Watershed Council August 2003 Abstract The Little Butte Creek Watershed Assessment has been prepared for the Little Butte Creek Watershed Council with funding from the Oregon Watershed Enhancement Board (OWEB). The Assessment was prepared using the guidelines set forth in the Governor’s Watershed Enhancement Board’s 1999 Oregon Watershed Assessment Manual. The purpose of this document is to assess the current conditions and trends of human caused and ecologic processes within the Little Butte Creek Watershed and compare them with historic conditions. Many important ecological processes within the watershed have been degraded over the last 150 years of human activity. This Assessment details those locations and processes that are in need of restoration as well as those that are operating as a healthy system. The Assessment was conducted primarily at the 5th field watershed level, that of the entire Little Butte Creek Watershed. List and describe field watershed levels below. Where possible, the analyses was refined to the smaller 6th field watershed level, thirteen of which exist within the Little Butte Creek Watershed. The assessment also notes gaps in data and lists recommendations for future research and data collection. It is intended that this document, and the Little Butte Creek Watershed Action Plan be used as guides for future research and watershed protection and enhancement over the next decade. The document was developed using existing data. No new data was collected for this project. Where data was lacking, it was detailed for future work and study. Acknowledgements This assessment was compiled and written by Steve Mason.
