The eight watersheds evaluated in Phase II of <br />this project were chosen from these lists. The SCS and BLM . <br />watershed selections resulted in agreement in the top four <br />watersheds and a coordinated decision was made on the . next four.. <br />watersheds. All the evaluated information was found to be of use <br />by the agencies in the decision making process. The ~atings fell <br />in a range. between a low rating of 3 and a high rating of 11.. The <br />selected watersheds were not all in the highest rated categories. <br />All the Phase I data as well as social, funding potential, <br />political, geographical agency work load and other pertinent <br />considerations were part of the selection process. The Phase I <br />inventory gave mahagers a detailed resource evalua,tiontool that. <br />permitted rapid and informed decisions to be made regarding <br />potential for improved land treatment in all the watersheds.inthe <br />Colorado River Basin. <br /> <br />, I"~ <br /> <br />The foll:owing eight watersheds were designated for Phase II <br />detailed evaluation: <br /> <br />14030001-070 <br />14060005-010 <br />14060005-020 <br />. 14060009-02.0 <br />14060009-030 <br />14070003-070 <br />14070007-010 <br />15010003-010 <br /> <br />Sagers Wash Watershed <br />Upper pariette Draw Watershed <br />Lower pariette Draw Watershed <br />Castle Dale Watershed <br />Ferron Watershed <br />Sweetwater Creek Watershed <br />Tropic Watershed <br />Kanab Creek Watershed <br /> <br />The complete listing of the resource inventory parameters by <br />watershed number is given in Table I of this Appendix.

The evaluation process characterizes the <br />present resource conditions and targets (identifies) critically <br />eroding areas within a watershed that have a high potential for <br />successfUl implementation of proposed land treatment practioes. <br />The evaluation process was performed by an experienced <br />interdisoiplinary technical team. The team used all available data <br />on the watershed and direct watershed observation to create .a <br />comprehensive model of resource conditions in the watershed. <br /> <br /><''':' ~ <br />
