 riencing heavy floods. Practically all streams are above normal. 



MAUI COUNTY FAIR EXHIBIT. 



An exhibit was shown at the Maui County Fair, consisting of 

 25 large transparencies showing both mainland and local field 

 work methods and results obtained therefrom, water-measuring 

 instruments, rain gages and methods of working up field data 

 into detailed reports. 



The exhibit was visited by about six thousand persons. 



OPERATION AND MAINTENANCE WORK. 



Kauai. The Hanalei and Olokele stream-gaging stations were 

 repaired and about twelve miles of trail in the upper Waioli, 

 Hanalei and Kalihiwai valleys -were cleared and repaired. 



At the suggestion of the governor of Hawaii, maximum and 

 minimum thermometers were established at Kokee, near the 

 center of the proposed Waimea park site, at the head of Waimea 

 canyon. 



Twenty-six stream and ditch-measurement stations and seven 

 rain-measurement stations were visited and 28 measurements 

 were made. 



Oahu. All stations on the island were visited and ten meas- 

 urements were made. Four rainfall-measurement stations were 

 also visited. 



Blue-print copies of data for the year ending June 30, 1916, 

 for the north and south forks of the Kaukonahua streams were 

 prepared and furnished to the Wahiawa Water Co., Ltd., and 

 the U. S. Army. 



Only minor repair work was done. 



Maui. The superintendent attended to the usual routine oper- 

 ation and maintenance work, visiting 17 stream-measurement sta- 

 tions and one rainfall station. Estimates were made for consider- 

 able repair work needed during December and January. Ar-

 horse by Mr; W. F. Pogue, for the use of employes of this divi- 

 sion in the ditch country.
