Abstract: 

This synopsis and synthesis of existing information on apparent changes in the Sonoma Valley watershed over the last two hundred years was compiled at the request of Rebecca Lawton, staff geologist and Prop 13 project manager for the Sonoma Ecology Center (SECSonoma Ecology Center is a not-for-profit organization located in the Sonoma Valley. http://sonomaecologycenter.org), and Lisa Micheli, watershed science coordinator for the SECSonoma Ecology Center is a not-for-profit organization located in the Sonoma Valley. http://sonomaecologycenter.org. Based on years of historical research, interviews with local elders collected for the Oral History Project, field observations, collaborations with watershed scientists, and preliminary analysis, the primary goal of this paper is to inform current Limiting Factors Analysis (LFAThe Sonoma Valley Limiting Factor Analysis. See http://knowledge.sonomacreek.net/node/3.), Total Maximum Daily Load (TMDL) and Army Corps of Engineers (ACE) studies in the watershed by:

-Outlining our current understanding of the historical record as it relates to issues of ecology, geomorphology, hydrology and fisheries.
-Documenting historical sources which relate to questions of historical ecology, geomorphology, hydrology and fisheries.
-Presenting a coherent and cohesive picture of the historic watershed (1810 to present) and to use this picture to extrapolate conditions in the reference watershed (pre-1810).
-Presenting hypotheses suggested by historical evidence which can be checked against modern field data.
-Defining directions for further historical and field research.
