in 1978, which added a process to allow for the creation of intensive groundwater use control areas. This addition to the statutes provided the chief engineer authority to implement more comprehensive corrective control provisions for water supply protection when local conditions require it or by the request of local stakeholders. Intensive groundwater use control areas were designated in McPherson in 1980 and the Pawnee River Valley in 1981. In addition, the enactment of the Water Plan Storage Act (1974) and the Water Transfer Act (1983) occurred under Gibson’s administration. 1983-2007 In 1983, David L. Pope became the fourth chief engineer and served for 24 years. Over his tenure, extensive rules and regulations were developed and adopted under the Kansas Water Appropriation Act, Obstructions in Steams, and the Levee Law. He also designated additional intensive groundwater use control areas in Burrton (1984), Lower Smoky Hill River Valley (1984), Hays (1985), Arkansas River Valley (1986), Upper Smoky Hill River Valley (1988), and Walnut Creek (1992). In addition, Kansas v. Colorado was filed in 1985 to enforce terms of the Arkansas River Compact. In 1998 Kansas v. Nebraska and Colorado also filed to enforce terms of the Republican River Compact. The Final Settlement Stipulation of the Republican River Compact occurred in 2003. For the Arkansas River Compact violations, damages exceeding $35 million were paid to Kansas in 2005-2006. Other milestones under Pope’s administration included the enactment of the Water Assurance Program Act (1986), Floodplain Zoning Ordinances Act (1991), and the Water Banking Act (2001). 2007-Current The present chief engineer, David Barfield has initiated the enforcement of the Republican River Compact Settlement in 2007 and concluded the Kansas v. Colorado litigation enforcing the Arkansas River Compact in 2009 in favor of Kansas. Barfield has worked to increase the development of groundwater modeling to analyze hydrologic conditions and for use as a tool to support decisions in water resource management. Barfield has ongoing dialogues with the Groundwater Management Districts and stakeholders regarding options to address areas with over appropriation of water resources, many of which are located in the Ogallala aquifer.
