<br />At Lamar the river started to rise at 4 a. m. June 5. At 8 a. m.
<br />the gage read 10.4 feet, and at 11 a. m. the crest height of 11.9 feet
<br />was reached. This stage continued until 1 p. m., when the river
<br />started to fall. The flood was 2 or 3 feet higher than that of 1904,
<br />the greatest flood previously recorded.
<br />At Holly the high~,ate.r mark was determined from levels after
<br />the flood to be abou{ 9.1Jfeet above the datum of the State gage.
<br />The discharge was estimtte.d as 120,00Q second-feet. I .

<br />The tributary streams below Pueblo chiefly affected by the flood
<br />were Fountain, Chico, and Salt creeks and St. Charles River. These
<br />streams, unlike the tributaries above Pueblo, which had a very high
<br />but short flood run-off, had sustained high stages. This .was due
<br />to the fact that the rain extended over the greater part cjf their
<br />drainage areas, and although it was not llS heavy as that over the
<br />smaller areas of the upper tributaries, it caused high stages in the
<br />streams, on account of the compar-atively large drainage areas. For
<br />the same reason the high run-off was not concentrated at one time
<br />but continued for 24 hours or longer.
