## About Agua Caliente

Agua Caliente here is the warm spring inside Roy Drachman Agua Caliente Regional Park, a Pima County park a mile or so from Tanque Verde. The water runs in the mid eighties, tepid. Access is open. This is county recreation land with a USGS record on the spring that reaches back decades, the kind of place you go to see the spring, since the temperature will not carry a soak.

Roadside inside a county park; the distance to the road is a couple hundred feet. Low desert elevation with a year that averages warm, little rain and almost no snow. Molino, a little over four miles off, is the campground the file lists.

The county park that holds the spring carries its name, Roy Drachman Agua Caliente Regional Park. The USGS water sample on record was taken in February 1942.

December through February are listed as best, which fits the desert. Park rules apply; the land is a county regional park, so check the park's own page for hours. No fee is recorded in the file, though a park may have its own. The chemistry on record is from 1942 and counts as history more than guidance.
