TABLE 38 



DAILY LOSS OF WATER FROM THE STREAM BETWEEN MIDDLE AND BRANCH 

 CONTROLS AND LOWER CONTROL IN COLDWATER CANYON 



June 25, to November 2, 1932 



During' the 54 days of full record in August, September, and 

 October, 1931, that is, during the latter half of the growing season, 

 the average loss from the stream between middle and lower controls 

 per 1000 feet of canyon per day was 0.25 acre-inch. 



For the 1932 season the record begins earlier, and during 124 days 

 of record in June, July, August, September, and October the average 

 loss from the stream between middle and lower controls per 1000 

 feet of canyon per day was 0.42 acre-inch. 



The record for 1932 is more complete and it was not interrupted 

 by rainy periods such as occurred in 1931. A graph of the use of 

 water in acre-inches between the middle and lower controls in 1932 

 is sliown on Plate XXIX. The measured daily use between controls 

 is shown, and through these points a smooth average curve has been 

 drawn. Ordinates to this smooth curve give the average daily use 

 between the middle and lower controls in acre-inches during any part 

 of the season, and the area between this curve and the baseline for 

 any period of time represents to scale the total use during that period.
