<br />As viII be noted from the preceding chart, the larger depletions bave
<br />occurred in the regions of limited precipitation where regulation of
<br />flovs and irrigation are primarily practiced.
<br />
<br />The following chart indicates the increasing runoff and the in-
<br />creasing depletions as one proceeds downstream along the Missouri River.
<br />
<br />
<br />Although there Is a substantial quantity of vater leaving the Missouri
<br />Basin much of this water bas served many purposes, such as municipal and
<br />industrial vater, irrigation vater, production of hydroelectric pover,
<br />use for recreation and fish and wildlife purposes, and for navigation. It
<br />can still be utilized more fully if we take care of it and maintain a suit.
<br />able quality. While the picture Is rather bright when considering the
<br />total Missouri Basin, there are parts of the Basin vhich do not have quite
<br />as favorable an outlook. Many of the areas have developments which currently
<br />utilize most of the available supply. Areas most in need of water resources
<br />use are generally lacking in the availability of the resources because of
<br />lo~ precipitation and high evapo-transpiration, ~hich gives less runoff.
<br />The planning effort in connection vith the Framevork Study will attempt to
<br />maximize the use of the available supply.
<br />
<br />Further .ark on estimated future conditions 'Jill be required, but these
<br />cannot be accomplished until at least the initial phases of the planning
<br />effort have been carried on. As tentative plans become available, appraisals
<br />viII be undertaken to assess the effect of such developments on the supplies
<br />of both surface and ground vater.
