Minimum Desirable Streamflows
In 1984, the Kansas legislature amended the Kansas Water Appropriation Act to establish minimum desirable streamflows (MDS) on four Kansas streams: the Marais des Cygnes, Neosho, Cottonwood and Little Arkansas Rivers. It also provided for the establishment of MDS on additional streams which were to be designated before July 1, 1990. Between 1984 and 1990, MDS were established on a number of additional streams. See the linked Act for a full listing of streams and the monthly schedule of MDS values at the specified gaging stations on those streams.
The statute further requires that the Chief Engineer to withhold from appropriation that amount of water deemed necessary to establish and maintain for the identified watercourse the desired minimum streamflow. All water appropriations with priority dates junior to April 12, 1984, are subject to MDS and may be regulated by the Chief Engineer, if deemed necessary, to maintain MDS.
The statutory provisions concerning MDS are incorporated into the Kansas Water Appropriation Act in K.S.A. 82a-703a through K.S.A. 82a-703c.
