Constructed wetlands were considered as an alternative to manage irrigation return water in an area of the upper Snake River Basin in south-central Idaho. A four-year demonstration project was undertaken to examine practical issues and performance characteristics encountered to effectively integrate wetland features with irrigated agriculture operations. The project activities included sites studies to evaluate feasibility and potential environmental consequences, wetland design and construction, and follow-up monitoring of the water quality and habitat values associated with the site features. Early review of results appears positive, although additional monitoring is needed to assess conditions as the wetland become more fully established. The project results are intended to be applicable to other wetland sites in the area and generally contribute to sustainable water use and more effective watershed management approaches.
