11 Letters between N.C. Grover, Chief Hydraulic Engineer and ECL about the differences in available water for irrigation between (USGS - ECL) and Reclamation 1920 (Whistler). ECL says not enough. Reclamation says plenty. Issues. Land available for Correspondence irrigation, ECL says as development increases, there will be more acres to irrigate. 44 pieces Reclamation drops acres off that they think won’t be developed, seemingly to make sure there is enough water. Reclamation didn’t appear to calculate evapotransporation. ECL believes that “...when ultimate development is near there will be a serious water shortage on the Lower Colorado.” Situation favors upper basin states that they can divert all the water they want and it will not cut off water to irrigation in lower CR. This is all after ECL’s report on Colorado River utilization. Therefore an entirely different policy needs to be developed.

Several pieces of family correspondence

Letter to Grover about hearing in San Diego on Los Angeles and Boulder Canyon project. He wants to go.

Southwest League to hold conference in Riverside in December. Permission granted to attend both of these.

Letter to Hon. Herbert Hoover suggesting he be his assistant with the Colorado River Commission (CRC). “I understand that the CRC Commission will prepare a comprehensive plan for the development of the water resources of the Colorado River basin. I assume that the seven interested States and the Republic of Mexico will require an equitable distribution of the waters of the Colorado, or an equitable distribution of the benefits to be derived from the complete development of the water resources of the basin.” 13 Letter from Grover and then from ECL asking for clarification. Grover asks him to be careful in what he says, only that he is in agreement. In terms of CRC meetings. 1922 Correspondence Letters to H. E Turner re Preston and ECL will visit their camp: drive from Yuma to 139 pieces Welton, thence south to Tinajas Altas, east over Camino del Diable to Tule tank and Tule well.

More correspondence about this, seems to be surveying areas in western which are irrigable from the Colorado River

Then to Pasadena, California then to Phoenix, Arizona.

More correspondence on irrigating all of Arizona

ECL made chairman of Arizona Engineering Commission - He is the only one not in controversy.

Letter from Norviel: Quinton of Quinton, Code & Hill, has made study of proposed high line canal from Boulder Canyon Reservoir, such as is proposed by Maxwell. And more on the September trip.

ECL to Grover about money, USGS should pay his expenses and salary while doing this work for Arizona since it will be information about the whole Colorado River project. Reclamation is paying for Preston. If USGS pays for ECL, then more money for the topographical survey.

Several letters on details of trip, re boats and logistics, who is hired or looking for work

Letter to G. E. P. Smith, Civil Engineer, University of Arizona., Tucson asking for his opinion on “... the height to which water may be pumped for the reclamation of land in Arizona.” “We must keep in mind that we are planning developments which may not be under taken for fifty years.” Smith’s 2pp reply

Colorado River Commission meeting in Santa Fe - working out the details of a compact

Newspaper article about Maxwell speaking to Jr. Chamber of Commerce about coming prosperity, irrigated and productive lands.

Governor elect of Arizona W.P. Hunt wants two years before entering an agreement, because Arizona lacks information as to the acreage irrigable from Colorado River and engineering works necessary to be built. Ariz cannot enter into agreement until the surveys have been made. Telegram from Herbert Hoover invites Hunt to meetings. Hunt sends Maxwell as his representative.

Norviel and Lewis both at Santa Fe

Dec 21, ECL to Grover, copy to Norviel. Returned to Pasadena yesterday. Finished 335 mile boat trip to Yuma Nov 18.
