October 31, 1969.

InOow into John Martin Reservoir during the irrigation season
totaled 132.520 acre. feet which is 84 percent of the t.wenty-year
a\'erage.

Total diversions downstream from John Martin Reservoir during the
period April 1 through Oclober 31, ]969. by the ditches in Colorado
Water District No. 67 were 107,505 acre-feet. Ditch diversions in
Kansas for the Sallle period amounted to 72,699 acre-feet.

Rivp.r l10w and reservoir releases April Ithruugh Oclober 31. 1969,
were 13:3,790 aCl'"e-feet which w<!s 46,<114 acre-feet less than the total

8. Gaging Stations

In general. strf>amfJow rp.l'ord~ of satisfactory accurac....: were
obtained at the Com pad :-ita Lions. Emphasis was continued on
performing additional field work to increase the accurac\' of the records
and on providing current streamflow data to the AdrllinistrJtion and
state officials as required.
It will be noted that there are differences in the releases from the
reservoir, as measured at the gaging station, and the daily demands by
C.olorado and Kansas. Perfect agreement cannot be obtained, but the
dIfferences could be minimized by relocating the gaging station nearer
