Resources for Arizona water professionals

Formed in 1985, AHS is a nonprofit organization dedicated to advancing hydrology and water resource research, planning, and development. We not only provide an open forum for professionals to exchange information, but we also support public understanding, education, and training in the science and technology of hydrology and water resources.

An important part of AHS’ mission is promoting the responsible use, management, and preservation of water resources in the arid southwest.

AHS is also dedicated to helping establish standards for the practice of hydrology as a profession. To support these goals, AHS funds meetings, scholarships, symposia, and other outreach and student activities.

On behalf of the Arizona Hydrological Foundation, I want to thank all of the AHS members and friends who donated to the Foundation through the purchase of Jeep raffle tickets.  We sold 158 tickets and netted $3,250 that will be used by AHSF to support the AHS internships and scholarships. I particularly want to recognize and thank Howard Grahn, AHSF Treasurer, for initiating and overseeing the ticket sales. Mike Hulst, AHS Corporate Board President, gets kudos for single-handedly selling 50 tickets!! The raffle ticket drawing will be held on Nov. 13.  You can check for more info.
