The variability of nature is the only constant in this system" and numerous, inter- related decisions must be made by several agencies as more and more information is obtained during each year about the availability of water, In the following decisional maps, we have tried to represent the range of steps taken during both a wet and a dry year to respond to differ. ent conditions of water availability. Under each major agency or cate- gory of agencies, we have listed some of the key decisions that must be made. Sometimes these are open to public review, often they are not. Public agencies make most of these decisions, but water users also play crucial roles, These maps are intended to convey the complexity of the system and also to list in a straightforward way some of the principal decisional cri- teria that control the storage and release of waters, For readability, we have consolidated many separate decisions in order to capture the breadth of issues relevant to management of the Rio Grande. In the next chapter we will examine some of the interests that are not fully reflected in the present management scheme. ',.."." ~
