the water in the river is colder than the
normal ground water temperature these will
show up on this infra-red chart.

Auguring test holes and installing obser-
vation wells for finite-difference studies of
evapotranspiration in the Arkansas valley was
started on April 12. Three additional finite-
difference sites are to be installed to evalu-
ate evapotranspiration in different parts of
the valley with different depths of water and
different vegetamon cover. One site has been
in operation near Lamar for about a year.

Field work is in progress to open high
altitude gaging stations to obtain records
during the spring runoff. If weather condi-
tions permit, field ~ork will begin in the
piceance basin studies the week of April 12th.
Did that start, Leonard?"

MR. NOOD:

"In the piceance basin? We went up there
on Thursday of last week for a couple of days."

MR. ODELL:

"Radio equipment has been installed on
gaging stations on the Arkansas River at Las
Animas and the Purgatoire River near Las
Animas. A recording received in Lamar pro-
vides stage data to facilitate administration
of the Arkansas River Compact. This equipment
was delayed considerably due to the difficulty
in obtaining the parts from the manufacturer.
It was ordered through the Leopold and stevens
Company and, of course, they don't manufacture
radio equipment so they had to wait on the
manufacturer before they could get the equip-
ment. They hoped to have it installed sometime
in January but we barely got it in in time for
the operation of John Martin Dam this spring.
It didn't take very long to run the water out
at John Martin; there was less than 4,000 acre-
feet in it when the gates were opened.
