USUBJ: Proposed Watering Regulations for 1989
On April 13 , 1989 , the Public Safety Commission unanimously voted
to recommend an odd/even sprinkling restriction for 1989 . This
I action was taken after an extensive presentation by Mr. Jay
Frischman, State of Minnesota, Department of Natural Resources ,
Ground Water Unit. The Commission took this action upon the
recommendation of Mr. Frischman, who presented information per-
, taining to water conservation throughout the state of Minnesota,
and in the City of Chanhassen, as well as surrounding com-
munities.
IIThere is no doubt that the time to conserve water on other than
an emergency basis is upon us .
II am attaching the information supplied by Mr. Frischman. Of par-
ticular importance is the information contained within the second
and third copies of the attached packet:
I1 . In Mr. 'rischman's letter to me, dated March 20 , 1989, he
points out that the Chanhassen City wells are in the Prairie
I du Chien-Jordon aquifer, which is the most heavily used
aquifer in the Twin Cities.
I 2 . On the hydrograph of the Chanhassen observation well, the
depth to water below land surface can be seen to be lowering
steadily ( this graph ends because the observation well was
filled in after 1986) .
IFurther support for entering into an odd/even sprinkling restric-
tion was obtained when you and I attended the Governor' s Disaster
I Management conference with Fire Chief Dale Gregory recently. At
that conference, information was provided to support Mr.
Frischman' s statement that the time for conservation of our
ground water resource is here.

In conclusion, such a sprinkling regulation would help provide
for a solution to potential short term water supply problems '
( usually dependent upon precipitation) , as well as to help con-
serve long-term needs by limiting the amounts of water taken from
the ground water resources.
Recommendation
It is the recommendation of the Public Safety Commission and the
Public Safety/Public Works Departments that the City of Chanhassen
impose an odd/even watering ban effective May 1 , 1989 (no
restricted hours are being considered initially) .
Director' s Comments : It is always easier to relax restrictions
than to try and implement them once the season begins . At some
point, if the much needed rains arrive, we can look at the '
problem and decide to relax restrictions .
