Hi again Southern AZ Stewards!
Those if you in the current Tucson MWS class heard about this project last
week - if you're available weekdays this would be an interesting and fun
project to get involved with!
>From Pima Association of Governments:
Here is a chance to get your feet wet in a Cienega Creek hydrology study
with Pima Association of Governments (PAG). Cienega Creek is a perennially
intermittent Outstanding Arizona Waters just southeast of Tucson near Vail
in the Pima County Natural Preserve. A headcut erosion feature that is
migrating up through the wetlands in the creek is being studied so that we
can better understand its impact on the habitat. The formation of headcuts
generally indicate that the watershed is out of balance in terms of
sediment. Within 6 years, the headcut has migrated 1200 meters, increasing
in size to 7 feet deep and 20 feet wide.
We need your help with Well Installation - either Oct. 23rd or Oct. 30th.
We will install two shallow monitoring wells, which will house data loggers
that will be used to measure any change in water levels as the headcut
migrates upstream. The work will include lifting and carrying equipment and
helping us hand-drive the wells into the ground!
If you are interested in helping, please contact Mead Mier by October 5th at
(mmier at pagnet.org) or 520-792-1093 x464. Please let her know which date is
best for you and the installation will be scheduled for the date with the
most volunteers available.
