Glenn, here's a bit of info that might be helpful... Mineral County has a commercial chipper that it rents out for $50 per day. It is a Bandit with diesel power that self-feeds 8 inch limbs. If you have slash and clean-up already stacked, one day of rental will produce a lot of great ground cover.
The reason I mention the chipper, is because you said you lacked a creek or spring. The following link is a video by a guy who started using mulch on his orchard and garden, and has not had to water his fruit trees for over 35 years even during drought.
The video gets a little long, but the first part is inspirational.
