Table 6. Diversion and return flows not used in water-balance calculations for the reach of the Klamath River, south-central Oregon.
[Flows are given in thousand acre-feet per year. Abbreviations: WWTP, wastewater-treatment plant; SSS, South Surburban Sanitation]
| Water use | Diversion flow | Return flow | |||
|---|---|---|---|---|---|
| Current | 1960s | Current | 1960s | ||
| Klamath Falls WWTP effluent | None | None | 12.00 | 2.50 | |
| SSS WWTP effluent | None | None | 7.60 | Less | |
| Other storm runoff | None | None | 2 4.00 | Less | |
| Lumber mills | 30 to 1.6 | Same | 0.90 | More | |
| Irrigated agriculture | 2 25.00 | Same | 4 6.25 | More | |
| Total | 25.00 | Same | 19.75 | Less | |
1Includes Klamath Falls Cogeneration Power Project plant evaporation losses.
2Estimates from PacifiCorp (2005).
3Lumber mills have combined water rights to 1.6 thousand acre-feet per year. Most of these rights are kept for fire suppression and the water is rarely diverted from the river.
4Return flows were assumed to be 25 percent of irrigated diversions.
