kea stream was discontinued as sufficient data have been secured 

 to rate this stream. 



In addition to the above 19 measurements were made and six 

 rain gages were read. 



From April 29 to May 1 a reconnaissance was made of the 

 streams in the vicinity of Hayula, and tentative arrangements 

 were made to estabhsh from four to six cooperative stations for 

 the Laie and Kahuku plantations. It has been proposed that, if 

 the plantations will purchase and install the necessary equipment 

 and materials, this division will furnish the supervising engineer 

 and will rate the stations. Should this arrangement be consum- 

 mated all windward (lahu streams will be under investigation, 

 except the Waianu, Waikane, Kahaluu, Waihee, Kaalaea. Ka- 

 luanui, and Kaipapau streams. 



An abundance of rain fell on Oahu during the month, and 

 all surface and underground storage was well replenished. 



Kaitai. 



Little was done on Kauai during the first part of the month 

 as Mr. Hardy left Waimea April 1 and Mr. Dort. his successor, 

 did not arrive until April 16. During this period Mr. Horner 

 spent all of his time constructing the new trail to the new Luma- . 

 hai station. This trail was completed on April 30. The latter 

 part of the month was spent on general maintenance and con- 

 struction work on windward Kauai. 



Six rainfall stations were visited and the stations on the Ana- 

 hola, Kapahi. and Kaneha ditches, the old station on the Lumahai 

 stream, and the station on the Halekua stream were discontinued 

 as having served the purpose for which these w^ere established. 



Maui. 



Only routine work was done on Maui with the exception of 

 the construction of foot bridges for flood measurements on the 

 Hoolawanui and Hoolawaliilii streams. Twenty-one stream and 

 five rainfall stations were visited, and twenty-two stream measure- 

 ments were made. 



An unusual amount of rain fell during the month, although 

 there were no extreme floods. The lowlands were unusually well 

 supplied. The Wailuku Sugar Co. did not find it necessary to 

 irrigate from March 25 to April 27. a period of 33 days. 



MAY PLANS. 



Oahu. 



A reconnaissance of the Laie and Kahuku streams will be com- 

 pleted and station sites selected.
