WORK ACCOMPLISHED. 



General Investigation of Heater Resources. It is estimated that 

 ninety-five per cent, of all streams and springs, both of govern- 

 ment and private ownership having a minimum discharge of one 

 million gallons per day or more, on the islands of Kauai, Oahu, 

 and Maui have been under observation during the year. There 

 has been more demand for these data, both by government offi- 

 cials and private water users, than ever before. The following 

 brief table shows the number of stations maintained during the 

 year : 



STREAM MEASUREMENT STATIONS. 



Ditch Flozv Investigations. A great amount of data relative to 

 the amounts of water diverted from Territorial lands by private 

 water users was collected during the year. All available ditch 

 flow records kept by private water users were collected and from 

 these, as well as from the ditch and stream flow records obtained 

 directly in the field by this division, a very fair approximation of 

 the value of the waters diverted from Territorial lands under the 

 various water licenses and land leases on the islands of Kauai, 

 Oahu, and Maui, has been made. These data, which were em- 

 bodied in a report to the Commissioner of Public Lands, follows : 



"The following table of water quantities and values has been 

 prepared from data available in this office. Records covering 

 periods of from three to six years are available for all important 

 ditches diverting government waters. 



"You will note that these data are segregated under two heads 

 — 'Developed' and 'Potential.' Under Developed are included the 

 waters diverted by existing ditches and other structures. Under
