A Picture is Worth a Thousand Words
This month marks the end of WRRC Director Sharon Megdal’s service as a board member of the Central Arizona Water Conservation District, better known as the Central Arizona Project (CAP). As a memento for her 12 years of service, Dr. Megdal was presented with the delightful caricature pictured here. It highlights her CAGRD and Underground Storage Committee membership, along with her serving as Board Secretary and Chair of this committee from February 2016 through 2020. Also pictured are key connections between her CAP Board service and her water work and research at the WRRC, including recharge basins that are important to CAGRD operations and Central Arizona water management. The WATEC folder to her left signifies her work connecting CAP Board members, staff, and many other Arizonans to Israeli technology and water management through conferences, seminars, and other means. The WRRC’s water map is featured in the upper right, and Sharon’s worry about getting back to Tucson in time for UArizona basketball games is reflected by the basketball on the shelf! And note the colors she’s wearing. In addition to expressing her appreciation of having the honor to serve as a member of the CAP Board, Director Megdal laughed when she saw what was written on the spine of one of the books by noting, “My students will appreciate that I emphasize adhering to the ‘that vs. which’ rule universally!”

BOR Article Series, Part 2: Lower Santa Cruz River Basin Study  
 
The following is part two of a four-part article series from our valued colleagues at the US Bureau of Reclamation (Reclamation). The series will cover the three Basin Studies currently underway in Arizona. John Rasmussen, Eve Halper, and Valerie Swick, Water Resource Planners at Reclamation, authored the series. Part three will be published in the December 18 issue of the Weekly Wave.
 
The Lower Santa Cruz River Basin Study (Basin Study) was proposed by the Southern Arizona Water Users Association and was initiated by the US Bureau of Reclamation (Reclamation) in 2016. Other cost-share partners include Pima Association of Governments, Cortaro-Marana Irrigation District, Central Arizona Project (CAP), Arizona Department of Water Resources and UArizona. The study area is identical to the Tucson Active Management Area (TAMA), which covers 3,866 square miles in Southern Arizona. Municipal use comprises the greatest portion of water demand in the TAMA, followed by agriculture. The remaining industrial demand is primarily due to mining.

Water Management Efforts on the Upper San Pedro River Basin
 
Last week's WRRC Brown Bag webinar, "Balancing Water for People and Nature: The Upper San Pedro River," featured Scott Deeny and Holly Richter of The Nature Conservancy. Their presentation provided an overview of groundwater data collected, current and future projects, and policies collaboratively developed over the past 20 years. The objective was to balance the water needs of the San Pedro Riparian National Conservation Area with the communities of Fort Huachuca. Richter opened the presentation with information on hydrologic monitoring efforts conducted by various partners, such as US Geological Survey, throughout the entire watershed. She also described the implementation of regional water resource management projects in Cochise County, which include the construction of aquifer recharge facilities. With the aid of groundwater capture maps and modeling, Deeny and Richter were able to identify the best areas to recharge and recover water. Both water experts would like to see urban-enhanced runoff used to recharge aquifers, but the legal status of the water added to the system by enhancements must be established to ensure its future recoverability.
 
Re-Imagining the Possibilities – AGU2020
 
Since 2017, Betsy Wilkening of APW has attended the American Geophysical Union (AGU) Fall Meeting to present the achievements of the Recharge the Rain (RtR) project, a NOAA-sponsored Environmental Literacy Program in partnership with Watershed Management Group. It is only appropriate, at the close of this very odd year, that APW’s presentation is about Re-Imagining the Possibilities. All of us are starting to realize that these possibilities translate into new opportunities for education, communication, and connection.

Karletta Chief Receives AGU Award
 
UArizona’s Dr. Karletta Chief was one of only 36 people to be honored with an AGU Ambassador Award and fellowship by the American Geophysical Union in 2020. WRRC Director Sharon B. Megdal, one of Chief’s nominators, characterized her as a trailblazer. An Associate Professor and Extension Specialist in the Department of Environmental Science doing research in watershed and unsaturated zone hydrology, Chief is also the Principal Investigator for an NSF-funded program that focuses on Indigenous food, energy, and water. Diné (Navajo) from Black Mesa, AZ, she received the AGU award for “pioneering” work “leading to transformative outcomes for Native American tribes and institutions.”
Congratulations, Dr. Chief!
 
New ADEQ Navigable Water Screening Tool Kit
                                                          
Facilities with a point source discharge of a pollutant into Waters of the US are required to obtain a permit under the Clean Water Act. Waters of the US are defined under the federal Navigable Waters Protection Rule and encompass ocean waters, permanent or perennial surface waters (present continuously throughout the year), intermittent tributaries that contribute to those permanent surface waters, and certain lakes and wetlands. Only 12% of the surface water in Arizona is known to be permanent, and therefore under federal jurisdiction. About 80% of stream segments have not yet been assigned a flow regime. The ADEQ has developed the Navigable Water Screening Tool Kit to evaluate the risk of a discharge being directly or indirectly connected to jurisdictional Waters of the US. This Tool Kit allows for a fact-based determination of surface water flow regimes, using a flow chart, the US Geological Survey StreamStats Flow Path Tool, and eMaps layers.
