Payette Project

Airborne and Ground-based Seeding

  • Seeding intended to enhance
  • Seeding intended to enhance

snowpack at the higher elevations above 4500’

  • Target area ~ 938 sq miles
  • Target area ~ 938 sq. miles
  • ~ 497 mi2 above the 6000’ level
  • 10 remote ground generators

– private property

  • Combined approach provides

more opportunities for addressing storms.

Payette Benefit Payette Benefit Summary

Benefits estimate using: Benefits estimate using:

  • USBR regression equation for Payette at Horseshoe Bend

– Using current 2008 conditions (near normal) g ( )

  • Precipitation increase of 10% from cloud seeding
  • Results in approximately 100 KAF of additional Mar – Jul runoff

Estimated cost of additional water ≈ $8 / acre-foot

Upper Snake Upper Snake Cloud Seeding Program

Water Year 2009: Water Year 2009:

  • Placed 3 remote generators to augment the manual network run by

the RC&D

– IPC Operated and Maintained these units

  • Provided Meteorology Support for the HFT project.
  • Operated a Radiometer in Ashton, Id
  • Provided a Rawinsonde and contracted and operator in Wilford, Id

Meteorology Support

  • 24/7 project support by 3
  • 24/7 project support by 3

experienced cloud seeding meteorologists

  • IPC generators are operated
  • IPC generators are operated

remotely from Boise

  • Use public data and IPC

Radiometer Rawinsondes and Radiometer, Rawinsondes and Weather Stations.

  • The meteorologist use this

weather data to determine weather data to determine which generators to turn on and

  • ff to seed most effectively.

Microwave Radiometer

  • Radiometers measure the power
  • Radiometers measure the power

radiated by the atmosphere at different wave lengths. They are passive, receive-only instruments, passive, receive only instruments, meaning they emit no radiation themselves.

  • The wave length of the radiation

The wave length of the radiation identifies the source of the emission resulting in a atmospheric profile: – Temperature Temperature – Relative Humidity – Liquid Water

2010 Objectives

  • Redesign remote generators summer 2009

g g

– Less Maintenance – Safety Faster and easier to deploy – Faster and easier to deploy – More cost effective – New generators will replace current units in the Payette

  • Add 7 to the Upper Snake for a total of 10 remotes

– IPC and RC&D are working on the locations.

  • Continued meteorology support
  • Continued meteorology support

– Rawinsonde
