On the Yuma project, Arizona-California, the Yuma Valley, 
which lies in Arizona, has been placed under public notice, but the 
pajanents have been contested by the water users' association. The 
Yuma Valley is exceedingly prosperous, having a gross yield for 
the year 1919 of $134 per acre, exclusive of live-stock increase. 
A successful sale was held in December, 1919, of a portion of 
the lands on the Yuma Mesa, which will be irrigated under the provi- 
sions of a special act of Congress, with water pumped from the main 
canal south of the city of Yuma. A contract has been executed with 
the Imperial irrigation district to connect its system with Laguna 
Dam and j)rovide better security for its water supply. 
The Orland project in California is regarded as the first unit of a 
comprehensive project for the development of the Sacramento Val- 
ley. It, however, stands alone as a self-supporting project, with an 
ample water supply from Stony Creek, a tributary of Sacramento 
Kiver, and has been practically completed. Public notice on this 
project was issued in 1916, and all payments are made promptly 
when they fall due by the association as a whole. Thus all the an- 
noyance, expense, and risk of delinquency are voluntarily shouldered 
by the water users' association, which has shown a commendable 
spirit of cooperation from the first. The project is prosperous and 
constantly growing in development. The only construction work in 
progress is a small amount of permanent canal lining, which was pro- 
vided for in the current public notice, and which is necessary for 
checking the seepage from the canals constructed in coarse material. 
The Grand Valley project in Colorado is delivering water to a 
portion of the land Avhich has been opened to entry and occupied by 
settlers. The agricultural operations are gradually extending and 
results are encouraging. The physical conditions in this valley are 
difficult on account of the seamy shale which occurs on the canal 
system and which has required a large amount of maintenance and 
betterment work to render the canals tight. Aside from these diffi- 
culties the works are operating in a very satisfactory manner. 
The Uncompahgre project, Colorado, is being operated by the 
United States under contract with the water users' association upon 
the payment of the cost of such operation by the association. The 
contract provides that the operation may be turned over to the water 
users' association whenever they so elect, and this is being consum- 
mated. The existing contract provides for the operation at cost for 
a period of five years, at the end of which period the project is to be 
opened under public notice unless further extension is made by the 
Secretary of the Interior. At that time, according to the contract, 
the construction repayments will begin. The construction of the 
project is completed so far as the plans of the Government have been 
made, but the distribution systems, which remain in the hands of the
