When a drainage system for an irrigation project does not control the
water table adequately, an alternative solution may be more practical than
further expansion and revision of the existing system. For example, if
water application to a given area raises the water table excessively, reduced
deliveries may bring about more efficient irrigation practices and thereby
lower the water table. If canal seepage losses are high, lining or sealing
parts of the delivery system may be necessary to control the water table.
The facts needed to determine whether additional drainage is the most logical
solution are often hard to obtain and require much background information
about water table records, water applications, crop water use, underground
strata, soils, and farming practices. A review of past records of other
investigators and the application of new techniques to analyze the entire
soil water system can result in an optimum soil and water management
program that may alleviate the drainage problem.

A problem area in south-central Idaho is being analyzed in a search for
an optimum solution. This paper is based on an evaluation of one year's data
and demonstrates a water budget analysis approach to the problem. The
study is continuing with further refinements.
