pended, but the records obtained (and freely furnished on re- 

 quest) have proved very valuable when compared and used in 

 conjunction with data obtained by this Division. 



Geographically the work has been extended very little and has 

 been limited to the islands of Kauai, Oahu, and Maui, — except 

 for a few rainfall measurement stations which have been estab- 

 lished on Molokai and Hawaii. 



From the viewpoint of intensity and efficiency, the work on 

 these first three islands has progressed tremendously. 



Floods. 



The year has been an exceptional one in regard to heavy rain- 

 fall, storms, and floods. The months of December and January 

 were notable for four or five heavy Kona storms which were 

 accompanied by the heaviest rainfall recorded since the U. S. 

 Weather Bureau was established in the Territory. These storms 

 resulted in the loss of more than a score of lives on Maui and 

 several deaths on the islands of Kauai and Hawaii. Damage to, 

 crops and structures to the extent of hundreds of thousands of 

 dollars also resulted from these storms. A great amount of 

 flood flow data were obtained by this division which will be very 

 valuable in future estimates for bridge, culvert, and flimie de- 

 signs. 



Legal Work. 



A large amount of hydrometric and other scientific work was 

 done in connection with the Waiakoloa water case, which was 

 tried at Waimea, Hawaii, and Honolulu in July, x\ugust, and 

 September, in cooperation with the Attorney General's Depart- 

 ment. 



Honolulu ^^'ATER Supply. 



The surface stream and ditch measurement work, started dur- 

 ing the previous year, relative to the future water supply of Ho- 

 nolulu, was continued on a wider scope than previously, and many 

 special reports thereon were furnished the Governor of Hawaii, 

 the Honolulu W^ater Commission, and others interested in this 

 problem. 



The artesian well records obtained by the Department of Pub- 

 lic Works show that, regardless of the heavy rainfall of the past 

 year, the amounts pumped and flowing from the wells have ex- 

 ceeded the supply, and one more year has been deducted from 

 the period which must surely end in a serious water shortage 

 for the city of Honolulu, unless one of the two following courses 

 of procedure is followed : 



1. The acquirement or control of all artesian wells in the
