It will be noted that during six of the nine storms enumerated above flood- 

 ing occurred. However, only the land immediately along the reservoir canal 

 was flooded and no great damage resulted, i. e., crops were not killed. 



In the detailed description of this district a number of conditions were men- 

 tioned that were responsible for these large rates of run-off. The small reser- 

 voir capacity places the pumping plant at a disadvantage during both heavy 

 and ordinary storms. It allows no reserve in the first case and in the second 

 the plant can not be operated at full capacity for lack of water; only one unit 

 can well be operated continuously until the water is removed. The pumping 

 plant on this tract has not yet failed to remove the water soon enough to pre- 

 vent any considerable damage to crops. By increasiug the storage capacity to
