I read in the paper that the Tempe City Council was going
to vote on preserving the Kirkland-McKinney Ditch. I think
these are pictures of the ditch located on the south-side
of 8th Street just west of McClintock Avenue.

"The Kirkland-McKinney Ditch was significant for its association
with the earliest agricultural efforts undertaken in the Tempe
district, and as the oldest remaining original manmade waterway
that was still in use in the Salt River Valley in the 1980s. The
canal was built about 1870 as one of the first organized attempts
to irrigate lands south of the Salt River."
