    Watershed Planning and Water Conservation

  • Currently IRZ is involved in developing a Regional Water Plan and all related engineering designs that meets the water needs of 4 municipalities, a group of irrigators, an irrigation district, and the local native American Tribes' fish enhancement project. This cooperative effort is a new design concept involving construction of a new river pumping station and 11 miles of 60 inch pipeline to expand the existing Phase-1 and Phase-2 of Project for enhancing fishery while maintaining the economic viability of the local Irrigation Districts.

  • Team member involved in developing a Comprehensive Watershed Plan to enhance fishery flow in the Salmon Creek in Washington State while maintining and enhancing existing irrigation use from the same river. IRZ was involved in design of a new 7,000 horsepower river station on the Okanogan River with 3.5 miles of 48 inch diameter pipeline. Included was also identifying and implementing district-wide water conservation measures.

    Watershed Survey

  • Conducted Aerial Thermal Infrared and videography survey of over 600 miles of Snake River and a dozens of its trubutries in Western Idaho for State of Idaho. The objective of the project was to quantify the river temperature; it involved GPS and GIS work.
  • Conducted Aerial Thermal Infrared and digital infrared for over 5000 miles covering two dozen rivers and streams for State of Idaho. The objective of the project was to quantify river temperature and riparian zone vegetaion assesment. It involved GPS and GIS work.
  • Aerial Thermal Infrared and digital near infrared survey of Umatilla River in Eastern Oregon for Oregon Water Coalition.
  • Aerial Thermal Infrared survey of John Day River, Grande Ronde in Eastern Oregon, for Stae of Oregon.
  • Aerial Thermal Infrared survey of Little Butte Creek and Rogue River for Oregon Department of Fish and Wildlife, Little Butte Watershed Council and US Forest Service.
  • Aerial Thermal Infrared to detect leaks in irrigation canals for an irrigation District in Washington State. This is an on-going project for the past four years.
  • Thermal Infrared survey of the Yakima River in Washington State.
