GROUND WATER BRANCH TECHNICAL MEMORANDUM NO. 66.05

To:       District Chiefs and Staff Officials

From:     Acting Chief, Ground Water Branch

Subject:  PUBLICATIONS - Revisions to Manual of Instructions for
                         Ground Water Punch-card System

Since the subject manual was released to the field in November
1964, many suggestions have been received for revising or
expanding a number of items of information included in the punch-
card system.  The manual will be revised as quickly as possible
and will be printed in quantity.  In the meantime, the adopted
changes (see attached) are being released in order that the copies
of the manual now in hand may be brought up to date.

The punch-card system, although in effect on a trial basis in the
Iowa, Florida, and Wyoming districts only, has been adopted
voluntarily by about a dozen other districts which have recognized
a need for it.

Several districts have requested that the new card-keyed well
schedule form be made available in a larger size.  Inasmuch as the
well schedule needs to be revised to reflect changes indicated in
the attached material, the revised form will be printed in two
different sizes:  (1) 5" x 8" as now used in the field, and (2) 8"
x 10" to provide additional space for those who now have
difficulty with the smaller form.  Please send a memorandum to
this office by February 15, 1966, indicating your preference and
also indicating the number of copies that you require in order
that we may determine the quantity to order.

Plans are underway to expand the punch-card system to include data
other than well and spring inventory data.  For your advanced
information water-use inventory forms and instructions for their
use are also attached; the inventory forms and cards for storage
of this information are being ordered in quantity.  A system for
automating water-level reports has been developed with the
assistance of the Kansas district; instructions and card formats
will be ready for release to the field shortly.

We shall keep you advised of further activities in the development
and use of the punch-card system.  Those interested in more detail
on any part of the system now in effect should contact this
office.



                                   (s) Gerald Meyer
