Columbia Snake River Irrigators Association The ColumbiaSnake River Irrigators Association Advancing Irrigated Agriculture and Water Resources Management The ColumbiaSnake River Irrigators Association CSRIA represents many of Eastern Washingtons most prominent farming operations with its members irrigating about 250000 acres of prime row crop vineyard and orchard lands. The CSRIA works directly with its sister organization the Eastern Oregon Irrigators Association collectively bringing about 400000 acres of irrigated lands into bountiful production. The CSRIA membership includes some of the largest and some of the smallest direct pumpers from the ColumbiaSnake River system relying almost exclusively on private capital to build and operate river pump stations and intricate water distribution systems. The members have farming operations that follow the ColumbiaSnake River system north from the City of Brewster reaching to the south along the John Day and McNary Pools.
