Description Every five years, The Office of Columbia River submits an updated long-term water supply and demand forecast to the Legislature. The 2016 Forecast will help OCR strategically fund water supply projects by improving understanding of where additional water supply is most critically needed, now and in the future. The Forecast provides a generalized, system-wide assessment of how future environmental and economic conditions are likely to change water supply and demand by the 2030s, and is evaluated at three geographic tiers: the entire Columbia River basin, Eastern Washington’s watersheds, and Washington’s Columbia River mainstem.

Using state of the art modeling techniques and economic scenarios, the forecast analyzes the impacts of climate change, regional and global economic conditions and state level water management actions on surface water supplies and irrigation demands across the Columbia River Basin.

NOTES The final report is split into three parts: The full report minus modules; the executive summary only, and report module appendices. The modules include information about key policy issues that may be addressed in future reports: declining groundwater, metric crop demand modeling, water banking, effects of user pay requirements for water permitting, and expansion of the forecast to include Western Washington. ********* The draft version of the report is also included in the parts section. ********* The 2016 Columbia River Instream Atlas is available under the related documents section at the bottom of this page.
