 | | Its 108,000 residents are supplied with drinking water from the north portion of the Santiam River, which has a watershed of 490,000 acres stretching from the Cascade Mountains to the city's intake on Geren Island (in the middle of the river) in the Town of Stayton. |
 | | Because the vast majority of land within the watershed of the north Santiam River is forested and there are few roads through much of the area, there is only a small risk of contamination to the water source. |
 | | To date, the MOU, titled "North Santiam River Cooperative Water Quality Monitoring Program," has involved a joint study between the agencies of the relationships between the forestry use trends in the federal and state lands and turbidity (a measure of cloudiness) in the water of the Santiam River. |
