Kevin Rein, State Engineer in the Division of Water Resources, introduced himself to the committee. The committee heard a previous discussion regarding the Republican River Basin on June 19, 2018. During that presentation, Mr. Rein discussed the need for possible legislation to modify the district boundary and the need for rule-making concerning the basin. Mr. Rein provided a brief background of the issues concerning the basin and described the final settlement that Colorado reached with Kansas in 2003 concerning water in the basin. The district purchased water rights and built the Compact Compliance Pipeline (CCP). This pipeline keeps Colorado in compact compliance and ensures that wells will continue to pump water throughout the district. The district boundary was defined in 2004 legislation, but the model domain used in the 2003 settlement is a hydrologic boundary rather than a geographic boundary. Mr. Rein discussed the boundary of the district and the impacts the discrepancy has on users in the district. The State Engineer's Office believes that the best solution to this problem is to amend the district boundary; however, there is not universal support to change the boundary. An alternate solution is rule-making promulgated by the State Engineer, which would include legally setting forth a requirement that well pumping requires a replacement of compact depletions.
