Economic Benefits

Based on how municipal/industrial water has been allocated in the Quad Cities in the past, the additional water supply is expected to generate:

  • 742 acres of residential domestic use, increasing the long-run tax base by over $485 million.
  • 101 acres of commercial use, increasing the commercial long-run tax base by over $65 million.
  • Over 6,500 jobs.

How economic benefits are calculated.


Statutory Authority

Without the agreement, the Quad Cities permit is interruptible under the Federal Columbia River Power System Biological Opinion (commonly referred to as the BiOp).  RCW 90.90.020(3)(c) requires OCR to find "new uninterruptible supply of water for the holders of interruptible water rights on the Columbia river mainstem that are subject to instream flows or other mitigation conditions to protect stream flows..."
