USGS Scientific Investigations Report 2012–5231  - Simulating Potential Structural and Operational Changes for Detroit Dam on the North Santiam River, Oregon, for Downstream Temperature Management  

Table 4. Minimum and maximum Detroit Dam outflow requirements for operational scenarios, North Santiam River, Oregon. 

[Details for operational scenarios shown in table 5. Flows are daily mean streamflow, in cubic feet per second (ft³/s). Altered flows are indicated by the numbers in italics. Other rules incorporated in outflow estimation: Daily maximum flow, 15,000 ft³/s; Maximum flow through power penstocks, 2,472 ft³/s. –, no maximum]
