CWA Board extends a heartfelt thanks to you, our volunteers - residents,
local businesses, technical partners - who have endured the heat,
pesky no-seeums, hours in the field, and numerous meetings to promote
research and to put projects on the ground within the Benson Subwatershed!
Readers need only to scan the contents of this newsletter to know
what has been accomplished through your efforts!!!!!!
have contributed hundreds of hours as in-kind match for an ADEQ
Title 319 Grant as they established an erosion control demonstration/
learning site featuring a 360' bank stabilization project, gabion-basket
structures, and loose rock check dams that work in series.
demo site that was constructed and is available for visiting is
a complete rain-harvesting collection and irrigation system that
delivers pressurized rainwater to contoured beds of drought tolerant
Volunteers have organized and hosted over 10 "how-to"
workshops related to both demonstration sites as well as additional
training sessions for xeroscaping, pruning trees, and accurate data
collection for CWA assisted monitoring projects with university,
city, state, federal, and non-governmental organization partners.
is the efforts of volunteers such as yourself that make it possible
for CWA to bring our communities guest speakers and consultants
who are leading resources in their fields - soils conservation,
contaminant control and water quality management, ecosystem sustainability,
water legislation, and other protections for the watershed.
we must thank all those volunteers who support us financially either
as members or through donations. All monies are used to
promote research, educational opportunities and materials . . .
. . and we are now only weeks away from becoming a 501 (c) 3 which
will be retroactive back to our conception!!!!!
WE SALUTE YOU!

RESEARCH LIBRARY ONLY A CLICK AWAY
ONE STOP RESEARCH
What is causing the sink holes around Benson and possible fixes,
2) What questions residents are asking the scientists about their
3) What does USGS say about our aquifer?,
and . . . . . .
Now, residents in the Middle San Pedro have a technical library
linked to ADWR, USGS, state and local entity reports relevant to
our area. CWA is partnering with Dr. Phil Heilman, Southwest Watershed
Research Center, to launch a CWA TAC WEB PAGE with over 80 links
to publications, reports, studies, and agencies with specific answers.
CWA Technical Advisory Committee chaired by Pamela Beilke, Director
of Compliance & Quality with Apache Nitrogen, continues to scour
archives, current journals, conference presentations, etc., to add
to descriptions and listings.
TECH Library includes a direct link to ADWR’s Water Atlas
– Volume Three a comprehensive review by the Department of
Water Resources of water supply and demand conditions for our area.
The Atlas consists primarily of maps, tables, figures and concise
text. The Atlas is designed to assist local and regional planning
efforts; identify water resource issues facing rural AZ communities;
compile recent information and update prior statewide water assessments;
identify areas requiring further study; and, develop and maintain
an online rural AZ database.
Water Atlas is only one valuable link provided by the CWA TAC WEBPAGE.
Users can navigate easily through the Middle San Pedro Research
Library, Research in Adjacent Watersheds, Current Research Projects
in the Middle San Pedro, On-going Data Bases, and Organization/Program

SUPPORTS AREA ISOTOPE STUDY
assistance from Cochise County Water Conservationist, Carl Robie,
CWA submitted an Isotope Proposal to expand the work currently being
done by the USGS within the Benson Subwatershed.
Board of Supervisors approved the requested funding that will extend
the USGS Study to include 12 additional carbon-14 measurements.
9 months, Dr. Chris Eastoe from the U of A Geochem Lab will present
at a CWA meeting the results of the carbon-14 data set with detailed
locations, and a preliminary report identifying whether/where significant
recent recharge to the regional aquifer is taking place.
will then be incorporated into USGS larger scale study.
here to review the Scope of Work and why such information is helpful.
WET-DRY MAPS AND STATISTICS ARE POSTED
new series of 6 maps of the of the San Pedro River,
surveyed in June 2008, has been posted to the CWA website.
San Pedro River wet/dry mapping dataset is a community effort to
track the river’s health by monitoring the persistence of
surface water during the driest time of each year".
south of the border at the head of the San Pedro downstream for
a total of nearly 120 miles, volunteers used GPS units to record
where water was present.
coordinated the efforts within the Benson Subwatershed, providing
training and equipment support for seven teams.

ASSISTS ASU WITH RIPARIAN MONITORING
several weeks in June, Dr. Gabrielle Katz and a team of ASU and
North Carolina students revisited riparian transects established
by CWA volunteers to collect the third year of streamside vegetation
Katz's team expanded data collection this year to include floodplain
vegetation at each of the three sites as well as recording the geomorphology,
or the cross-section profile, of the stream channel.
owners participating in the study received a list of plant species
found within the randomly placed plats (a 1-meter square frame)
at their specific site.
Benson sites are included in the scope of work funded by an Arizona
Water Protection Fund Grant from ADWR.

FOR CITY OF BENSON'S RESTORATION PROJECT
assistance from the Coronado RC&D and NRCS, the City of Benson
was awarded funding for their San Pedro River Habitat Improvement
Project by the U.S. Fish & Wildlife Service.
project area is 12 acres in size and is located within a 100 acre
tract owned by the City of Benson along the San Pedro River. The
parcel is abandoned cropland located within the City limits, just
north of Interstate 10. The parcel is adjacent to the golf course
and sewage treatment ponds and includes a one mile reach of the
first step planned for the project was to increase the species diversity
of plants on 10 acres of upland adjacent to the river by reseeding
to native plants in the open areas.
second step would be to remove the tamarisk from a 50' reach of
the river under the El Paso Natural Gas overhead pipelines. The
tamarisk poses a fire danger.
Killeen, TNC Biologist on the CWA Technical Advisory Committee,
developed the photomonitoring protocol and trained CWA Volunteers
to do semi-annual data collection photography.
Jan. Photo Log recorded the temporary delay in restoration efforts
due to an increasing number of sink holes developing in the area,
some ten to twelve feet deep.
introduced Ray Harris, formerly with the Arizona Geological Society,
to Kathy Suagee, project lead. Ray Harris walked the site with Kathy
Suagee, City Council and Bob Nilson, Visitors Bureau. CWA shared
baseline information on the sink holes and used GPS readings and
records to distinguish between older sink holes and those more recently
Harris met with City Staff multiple times to share his research
on sink holes and desiccation cracks in the area - contributing
to the City Staff's plan for successful management.
August Photo Shoot recorded new efforts with an absence of sink
holes! (Consider volunteering for this 2.5 mile hiking opportunity
with the bonus of wildlife viewing - definitely a pleasant, early

BUILDING LOW MAINTENACE DIRT ROADS
"dirt roads that lay easy on the land" is Bill Zeedyk's
forte and is representative of his life work. Zeedyk is a retired
U.S. Forest Service Biologist whose expertise includes "building
and maintaining unpaved rural roads so that they drain effectively,
harvest water in appropriate places and decrease soil erosion and
is hosting a workshop on October 11, 10 A.M. to 2:30 ish where Zeedyk
will share his publications showing how roads can be managed to
improve the health of a watershed.
workshop will go between two sites: the Power Point discussion to
be held in the St. David Water Improvement District's Office and
then moving to the CWA Manzanita Erosion Control Site for discussions
of appropriate strategies for real on-the-ground challenges.
Road Blading Workshop is the fourth in a series of "how-to
workshops" funded by a $ 47,000 ADEQ Title 319 Grant. CWA is
administering and providing project support on 180 acres where property
owners have joined together to develop a set of complimentary best
management practices for reducing upland erosion.

WATER - STATE DISCUSSIONS
of the Benson Subwatershed watched State Legislators carefully as
budget cuts swept across the board - fearing the worst for ADWR
Rural Watershed Initiative Funding.
ADWR received a $500K cut, Tom Whitmer, ADWR Statewide Planner,
assured CWA members that the hydrological investigations contracted
with USGS will continue as originally planned for the 2008 fiscal
contract negotiations, ADWR and USGS continued discussions regarding
the development of a meaningful product to represent the findings
of the airborne geophysical study conducted last year. CWA TAC will
keep the membership apprized of its development.
here for a quick overview of the study.
Cochise County has adopted the Water Adequacy Standard, the Board
of Supervisors continue to play an important role in dicussions
as ADWR prepares revisions to the Adequacy Rules.
County was the first County to adopt the Adequacy Standard that
requires developers to show they are able to provide a 100 year
water supply for their project without drawing the groundwater table
1200 feet below ground level.
County's interest is primarily two fold: 1) the County would like
a policy to be deveoped that will provide assistance to the small
developer (30 units or less) so that the developer does not chose
to wildcat in order to avoid the expensive water analysis, and 2)
to assure leniency so that drylot subdivisions are considered on
an individual basis rather than the current policy which identifies
a subdivision as having an inadequate source of water if the groundwater
table is lowered below 400' from the ground's surface. This is of
particular concern is areas such as Portal where groundwater levels
are over 600' below ground surface.
following are highlights from ADEQUACY RULES UPDATE provided by
Tom Whitmer at CWA's August monthly meeting.
- The Department
requested all informal comments be submitted to the Department
by August 15.
written comments are being reviewed with several more expected.
The most controversial issue is up on the Coconino Plateau where
the groundwater level is greater than 3,000 feet below ground surface.
ADWR is to present at an upcoming Coconino BOS meeting which is
expected to produce another round of questions.
to the delays with Coconino Issues and the development of a new
way to address physical availability in several northern aquifers,
it will probably be 5-8 weeks before a draft is published in the
Register with the Secretary of State.
is working on a schedule of next steps – dates for completion
of summary and submission to Secretary, closing the record, hearing
Dates and GRRC meeting dates with eventual effective dates.
