WARMING IN THE SOUTHWEST
An Overview presented by Dr. Michael Crimmins, Climate Science Extension
Specialist, U of A
28TH 6:30 P.M. BENSON CITY HALL
- How settled
is the Science, how big the controversy?
- What are
the projected changes in temperatures, precipitation, and impacts
to water supply and the landscape?
- What is
currently being done to reduce green house emissions?
- What can
we do as individuals?
findings and projections are based on consensus of hundreds of scientists
from the 2007 Intergovernmental Panel on Climate Change. Additionally,
several key climate change studies published in 2008 and 2009 will
be covered and discussed with respect to policy implications and
ADWR FACING DEBILITATING BUDGET CUTS
is growing unrest and concern among constituents as proposed budget
cuts to ADWR would require a cut up to 105 of their 182 employees
in addition to the 50 vacancies that are currently frozen. With
such limited staff, it is an impossibility for ADWR to protect Arizona's
existing water supplies and provide sustainable water supplies for
our future needs. A sustainable water supply is essential for economic
recovery and growth.
letter from ADWR Director Herb Guenther to the House and Senate
addresses this "unprecedented budget crisis" that disportionally
cuts ADWR's budget 56% below their FY 2008 budget while the rest
of the state agency budgets average a 20% reduction.
is suggesting that their base budget be increased to $18.4 million
and take $8.3 million directly for the Arizona Water Bank Authority
Nevada resource account (incentive/insurance) account for the General
Fund. An $18.4 million base budge for ADWR would represent a reduction
of 20% consistent with other state agencies.

WATER INSTITUTE LOSES FUNDING
Arizona State budget for year 2009 contains $142 million in cuts
to the university system, with more reductions anticipated for 2010.
As a result, University officials eliminated the Water Research
Institute of the UA, ASU, and NAU.

some of the state's major water-supply issues and water-quality
Some of the projects that were approved for this year will move
forward, but over 15 will not - and all the funding from this fiscal
year that remains will be returned to the state to help make up
UA has a separate Water Resources Research Center and ASU conducts
research at its Global Institute of Sustainability.
SCIENCE STUDY UPDATES
Water Well Use Study - Cooperative Extensions and U of A:
a temporary "equipment" snag, plans are moving forward
to install monitoring devices on volunteered-domestic wells throughout
2007, the UA Cochise County Co-operative Extension, the Water Resources
Research Center, and SAHRA began recruitment of volunteer well owners
to participate in this study to obtain information about this groundwater
use. Only a few meters had been installed in a small sampling of
wells before it was determined that an equipment adaptation was
will now focus on completing the installation of over one hundred
meters to collect data for a significant period of time to be useful
to decision-makers. Data will not be presented in a format that
will allow the identification of any site or home-owner, but rather
will be presented in a category based on the characteristics of
the group, e.g. lot size less than 2-acres, 3-4 people, etc.
County contributed $100,000 toward the project since it is difficult
managing water resources without a realistic figure for water use
by more than 11,000 private wells within the County. The current
figure used is roughly 800 gallons per day per household of 2.5
people on 4-acre parcels.
Isotope Expansion Study:
collection funded by Cochise County for 12 additional carbon-14
measurements has been completed within the Benson Sub-watershed.
Chris Eastoe from the U of A Geochem Lab reported that although
the expanded data-set for the USGS Study has been collected, the
interpretation will not be completed until later in the summer as
to whether/where significant recent recharge to the regional aquifer.
a deliverable for the funding support, CWA will host a public forum
tentatively scheduled in August so that Dr. Eastoe and USGS representatives
may present the results and be available to answer community questions.
here to review the Scope of Work and why such information is helpful.
Hydrological Investigation in the Benson Subwatershed:
continues the study to quantify the total water in storage, location
and quantity of recharge and evaluate historical changes within
the watershed. The Benson study is the only hydrologic investigation
that is currently being funded by ADWR Rural Watershed Initiative.
It is uncertain how the study will be modified with the new proposed
here for brief summary of time line and objectives.
SAN PEDRO MONITORING PARTNERS GEAR UP FOR 2009 WET-DRY STUDY
The Nature Conservancy, CWA and other partners are meeting to finalize
the logistics in monitoring nearly 120 miles of the San Pedro River
from below the Mexican border to the town of Winkelman on June 20th.
to eight teams of three volunteers each are being recruited for
training in the Middle San Pedro area so that standardized use of
GPS units and forms produce quality data. The wet/dry mapping dataset
then historically tracks the river’s health by monitoring
the persistence of surface water during the driest time of each
has coordinated the efforts within the Middle San Pedro for three
years, extending the ten-year program developed in the Sierra Vista
Watershed by BLM and TNC.
ATVs, and hikers will be on the river from approximately 5:30 A.M.
to approximately 11:00 A.M.- traveling stretches of the river varying
from 3 to 8 miles across lands to which property owners provide
is your opportunity to join this year's efforts. Volunteer for parts
of the river seldom traveled where perhaps deer, javelina, teal,
turtles, minnows, and lots of fresh track can be spotted. From intermittent
water south of Benson, to dry white sands to the north, it makes
for a great morning outing. Call 609-2738 or email email@example.com

COMPLETES MANZANITA EROSION CONTROL PROJECT
February, CWA submitted its final report and received the last reimbursement
check to officially close the Manzanita Erosion Control Project.
Earlier, the eight property owners hosted a Field Day on the 180-acre
site just south of Benson off Hwy 80 - sharing with the public the
results of a 3-year learning lab made possible with an ADEQ Title
319 Grant. Click here for photos of the wagon train!
managed the $ 47,400 project with property owners and volunteers,
hosting workshops with hands-on training of Best Management Practices
to prevent upland erosion and decrease sediment transport to the
San Pedro River. The following "on the ground" projects
were constructed as models for future individual projects.
- a 350' plus ' bank stabilization
- an appropriately-sized replacement culvert
- a nine-basket gabion structure to arrest head cutting,
- dirt road drainage interventions
- multiple grade stabilization structures such as loose
- check dams and wire sausages.
Property owners and CWA extend a major thank-you to the
ADEQ Grant Management Team and partners who supplied materials,
training, technical expertise, and encouragement until the very
last rock was placed:

Final Field Day
USDA-ARS PRESENTS EXCITING PROJECT TO CWA TECHNICAL
Dr. Phil Heilman, Agricultural Research
Services, presented the CWA TAC team with an exciting proposal -
a partnership to develop informational Google Flyover videos as
an educational outreach tool for the Benson Subwatershed.
After viewing a demonstration, TAC saw
the benefits first hand as they were technologically taken on a
guided tour of the watershed in "a glass-bottomed helicopter
to see how land ownership overlaid the watersheds in the Middle
San Pedro" - never leaving the comforts of the conference room!
Being able to provide the equivalent of
such a tour as a narrated video, accessible to anyone with a browser,
would be instrumental in helping watershed stakeholders expand their
understanding of natural processes and human activities beyond the
specific locations with which they are most familiar to what is
happening across the watershed as a whole.
CWA would like residents and interested
parties to suggest topics for the list being created by TAC so items
can be prioritized, expert resources identified, and scripts created.
First formal videos should be ready for
the TAC LIBRARY and public viewing toward the end of June.
SPEAKER SERIES COMPLETED
ended our Riparian Speaker Series - a program designed to help us
better understand the challenges of balancing Human Demands and
those of the Environment.
prepare for the series, a task team developed a pictorial review
of key resources suggested by members of the Upper San Pedro Partnership
Technical Advisory Committee. Our foundation included the Hereford
Report, The Changing Mile, and Ribbon of Green - all with specific
information related to our area.
