193 



During" the latter part of the month heavy rain storms occurred 

 in the Hilo, Hamakua and Puna districts on Hawaii ; and at sev- 

 eral points on Kauai, Maui and Oahu. At Hana, Maui, on April 

 27, 24.3 inches of rain fell in three and one-half hours, and a 

 great damage was done to roads, bridges and crops. On Oahu 

 heavy rainfall during the last week of the month enabled us to 

 obtain much needed flood measurements on the stations main- 

 tained in cooperation with the Kahuku and Laie plantations. 

 These stations were established to determine the feasibility of 

 storing storm water in that vicinity for irrigation of fields that 

 are now irrigated by pumped water. 



On Kauai heavy rains fell after April 20. On April 27th four 

 inches of rain fell on the AIcBryde Plantation, and the Wainiha 

 Power Plant was shut down as not being needed, — the first time 

 in three years.
