Three sets of seepage measurements were made at ten canal sites and at all turnouts along a 15.3-mile section of the Central Utah Canal during the sumner of 1986. The total loss for the 15.3-mile section averaged about 36 cubic feet per second or 2.4 cubic feet per second per mile. The nine subsections were grouped into five reaches of one or more subsections with similar losses per mile. Average losses for these five reaches ranged from 0 to 4.1 cubic feet per second per mile. No average gains were detected.
