Alluvial Valley Floors (AVFs). During the recent reconnais- <br />sance investigation of the Red Canyon Mine site and vicinity, the <br />following points were clarified: <br />1. The agriculturally useful vegetative communities present on the <br />valley floors of Ward and Williams Creeks do not indicate that <br />subirrigation is occurring. The water levels in the two alluvial <br />wells near Ward Creek also indicate that the water table is too <br />deep for subirrigation to be occurring (see Appendix B). <br />2. The irrigation practice presently occurring in the Ward and <br />Williams Creek valleys is clearly flood irrigation. <br />3• Large are ~r amlaid deposits are present <br />--~ <br />ahd are d in the Ward and Williams Creek <br />valleys. <br />Based on the points mentioned above, it is apparent that the Ward <br />Creek and Williams Creek valleys have characteristics indicative of AVFs, <br />(However, certain water supply questions,as noted below, need to be <br />6 <br />
