There are many stories about the early western wars over water, gold, cattle, development, etc.  If you like the fictional but based on some actual or likely stories, some of Louie Lemour book series may fill the bill.  Many of the old cowboy movies had integrated stories about water, cattle, land, mining, timber, etc., those who have rights to it, and those that wanted to take it. There are many technical references concerning water, water rights, water law, old court cases, etc.  So much information, it would take years to read. Since you are in Colorado State, you should contact the hydrology school and I would bet there is one or more classes that address water rights.  Instream flow needs and channel maintenance flows are also HOT topics in some areas.
