“Along Cherry Creek from the [Denver] city limits to a point about a mile above its mouth the flooded area covered a block and a half on the north bank and a half a block on the south bank… In all, 86 blocks in the residential district and 19 blocks in the business district were inundated…

From statements of residents throughout the basin it appears that the heaviest precipitation occurred in the lower half of the basin, extending from Franktown to a point about 5 miles north of Denver, and that the rain was particularly heavy below Parker. In this section the rain was so intermingled with hail and came down so fast that it was said to be difficult to see a hundred yards. The precipitation above Franktown was slight and, according to J. E. Field, did not extend to Castlewood Dam… The rain caused every dry gulch to run bank full, and as the storm apparently traveled down-stream at about the same rate as the water in Cherry Creek, the cumulative effect was nearly the maximum for a storm of that intensity.”
