The '''Columbia Basin Project''' (or '''CBP''') in Central [[Washington (state)|Washington]], United States, is the [[irrigation]] network that the [[Grand Coulee Dam]] makes possible. It is the largest water reclamation project in the United States, supplying irrigation water to over {{convert|670000|acre|km2}} of the {{convert|1100000|acre|km2}} large project area, all of which was originally intended to be supplied and is still classified irrigable and open for the possible enlargement of the system. Water pumped from the [[Columbia River]] is carried over {{convert|331|mi|km}} of main canals, stored in a number of reservoirs, then fed into {{convert|1339|mi|km}} of lateral irrigation canals,<ref name=75years>{{cite journal |last= Bloodworth |first= Gina |author2=James White |year= 2008 |title= The Columbia Basin Project: Seventy-Five Years Later |journal= Yearbook of the Association of Pacific Coast Geographers |volume= 70 |issue= Annual 2008 |pages=96–111 |issn= 0066-9628 |url= http://muse.jhu.edu/journals/yearbook_of_the_association_of_pacific_coast_geographers/v070/70.bloodworth.html |accessdate= 30 May 2013 |doi=10.1353/pcg.0.0006|s2cid= 128572803 |doi-access=  |url-access= subscription }}</ref> and out into {{convert|3500|mi|km}} of drains and wasteways.<ref>{{cite web |title= Project details - Columbia Basin Project |publisher= [[United States Bureau of Reclamation]] |url= http://www.usbr.gov/projects/Project.jsp?proj_Name=Columbia+Basin+Project |accessdate= 25 October 2009 |archive-url= https://web.archive.org/web/20150215125327/http://www.usbr.gov/projects/Project.jsp?proj_Name=Columbia%20Basin%20Project |archive-date= 15 February 2015 |url-status= dead }}</ref>  The Grand Coulee Dam, powerplant, and various other parts of the CBP are operated by the [[Bureau of Reclamation]].
