Water Source Inventory Project on the Tonto National Forest

Geocaching with a purpose and it's Fun!

Do you like to hike or ride on the Tonto National Forest?

Would you be interested in having a mission on your hikes/rides?


Friends of the Tonto is looking for individuals, or perhaps a group, who would be interested in helping inventory water sources that have been developed for use by livestock and wildlife.  These water sources are one of 3 types:


  •  Windmills with troughs
  •  Springs with concentration boxes constructed at the spring source, with a pipeline that gravity-flows water to a trough and/or large storage tank
  •  Stock tanks – these are not really tanks, but are small ponds that have been dug out in drainages to collect runoff water.  These are typically earthen structures.


This project includes all of the Tonto National Forest:  We have however prioritized Blackjack and New River in the Cave Creek Ranger District.  The New River Allotment centers on the New River drainage, from its headwaters under Cook’s Mesa downstream to the boundary with State land.  The Blackjack Allotment is the area north of Seven Springs and south of Bloody Basin.  Information collected will be used to create a more accurate map of water locations & their construction for this environmental analysis.
