REPORT OF THE WATER RESOURCES DIVISION

U, S. GEOLOGICAL SURVEY

January 14, 1966

In the interest of more efficient operations, the Colorado District
offices for water-resources investigations were moved in mid-December
into new office space at the Villa Italia Shopping Center at Wadsworth
and Alameda near southwest Denver, The Water Resources Division occupies
rooms 260-288 on the second floor of Joslin's Department Store. The
mailing address is U. S. Geological Survey, Water Resources Division,
Building 25, Denver Federal Center, Denver, Colorado 80225. The tele-
phone numbers remain unchanged.

At the same time, the units attached to the Office of the Area
Hydrologist were moved from Ammons Street to space at the Federal Center
previously occupied by Ground Water personnel.

Runoff has continued to be much above normal for most of the State
since last June, Streamflow records at key gaging stations indicate
that runoff for the 1965 water year for the mountain area waS about
130 per cent of normal except in the Arkansas River basin where it was
about 175 per cent. This is considerably less than the runoff for the
1957 water year which was about 180 per cent of normal with 200 per cent
in the Arkansas River basin.

Computations have been completed for indirect measurements of flow
at more than 100 sites for the June 1965 floods in the Arkansas and
South Platte River basins. The results can be obtained from the district
office of the Surface Water Branch.

Changes continue to be

on January 18.

Field work in the Piceance Basin was completed in October and pre-
paration of data for the final report is now underway.

Water levels were measured in observation wells in the S.rn Luis
Valley on January 11 and 12. Water levels rose from 1 to 14/feet and
averaged about 4 feet higher than when measured in November of 1964.
A mass measurement of water levels in about 450 wells in the High Plains
was begun on January 24th. Four men from the USGS and one from Colorado
State University are participating.
