The time of their arrival was between T and 8 p. m. June 3. These crests were probably greatly diminished in volume when they reachcd PueLlo, being affected by the natural storage in the river channcl. Although the heavy rains continued during the afternoon and eyening, and a considerable volume of water re:tChed the Arkansas. during that period, no more flood crests reached Pueblo until late in the evening. From 10 p. m. until millnight the floods from the tributaries near Pueblo, which were the streams having the greatest flood discharge, reached the city. At the R:\me time the flood crests from the most llistant tributaries also arrived. As the riyer-chnnnel stol'Ul!:e became less with increasing stage, the luter flo()(ls must have reached Pueblo in much more nearly their original volumes than the earlier ones. The effect of the arrival of nil thesl' {loo,1 crE'sls is shown 011 the aC- companying hydrograph (fig. L p. 28). lILu:urUlIr nISCHAm;E.
