 hours. 



4. Kahuawai Spring, elevation 590 feet. 320,000 gallons 24 

 hours.

 There is no way of measuring the amount diverted 1)\- the 



Pacific Heights pipe line. 



iVil of the above sources were being diverted by irrigation 

 ditches. The stream below the road crossing at an elevation of 

 about 250 feet being dry. 



A comparison of these amounts of water with the amounts 

 found previously show that the Pump House Spring (elevation 

 630 feet) and the Kahuawai Spring (elevation 590 feet) have 

 decreased about ten per cent., while the Kaikahi Spring (elevation 

 275 feet ) has decreased more than 60 per cent. 



Extremely dry weather has prevailed, the February rainfall be- 

 ing extremel}^ light- Indications point to even a smaller dis- 

 charge from these springs during the coming summer and fall 

 months. 



As the season ])rogresses, additional measurements will be made 

 and the results furnished to you. 



.Attached hereto is a copy of a memorandum showing previous 

 measurements.
