Project Officer 0 Larry Marxer Field Crew amp Research Leader This watershed sub basin is located somewhere in Oregon It has a combination of urban communities privately owned agricultural lands and public forest and range land The watershed contains approx 2500 miles of permanent and intermittent streams most of which have populations of anadromous and resident salmon and trout population as well as assorted warm water fish species The impact on water quality in the streams in the watershed continues to grow as a result of increased runoff from urban development agricultural production and logging Local residents within the watershed have become concerned about the increased threat to water quality and are making plans to work with government agencies and local business and industries to address problems through the development of best management plans The basin assessment completed by the watershed council revealed that there is very little baseline water quality data available which could be used to identify specific problems or be used for planning purposes and future comparisons The participants in this project including the watershed council Oregon DEQ ODA and State Forestry want to document the baseline ambient water quality conditions of surface water streams in the basin The data collected will be used by the watershed council and state agency staff to characterize current
