42 
covers L27 acres, and has a claimed capacity of 2,500 acre-feet. Nos. 
2 and 5 have a combined capacity of H5 acre-feet. The reservoirs at 
present serve about 800 acres. 
THE CHAPMAN RESERVOIR. 
The Chapman Reservoir covers about 70 acres in sec. 32, T. 5 N., 
lv. 69 W., and irrigates probably not more than 80 acres. Another 
smaller reservoir in the same section is used for stock purposes prin- 
cipally. 
Some other sites and reservoirs exist under the Handy Ditch, but 
little could be learned concerning them. The Smith and Welty Lake, 
in sec. 15, T. 4 N.j K. 68 W., has an area of 25 acres and a capacity of 
loo acre-feet. The Berthoud Lake, in sec. 11, T. 4 N., R. on W., has 
an area of -±o acres and a capacity of 250 acre-feet. The Welch Lake, 
in sec. 25, T. 5 N.. R. 69 W., has an area of 30 acres and a capacity of 
200 acre-feet. In sees. IT. 20, and 21, T. 4 X.. R. 69 W., are some 
very fair reservoir sites. Mr. George Zwick owns a good site in sees. 
17 and 20, T. 4 N.., R. To W. W. T. Newell has a site in sec. 18, T. 
& N.. R. 68 W.. with an area of about 150 acres. It could be tilled 
from the Handy Ditch and furnish probably 1,500 acre-feet of water. 
In the tilling- of reservoirs under the Handy Ditch the stockholders 
are permitted to store water in proportion to the amount of their 
stock, if they prefer to do so. As between themselves, the water is 
always divided in proportion to the stock held by each, and no restric- 
tions are placed on the u9e to which it is put. On account of the 
smallness of its first priority and the necessary abundance of water in 
the river before the ditch can draw on its second priority, it is not 
possible to store water " needed by other ditches for direct irrigation." 
Whenever the ditch is running 50 cubic feet per second or less it is 
probable that every user needs his full amount for direct irrigation. 
RESERVOIRS UNDER THE HOME SUPPLY CANAL. 
The reservoirs under the Home Supply Canal are both large and 
important, and the values of the water rights and of the land equal the 
oldest rights on the river. 
It is estimated by those best acquainted with the practical working 
of the Home Supply system that at least three times the area is now 
irrigated that could be served without the Mariano and Lone Tree 
lakes; that i> to say. L8,000 acres are now irrigated in place of the 
(),000 possible with the ditch alone. The land is estimated to be worth 
two-fifths more with than without reservoir rights: its value under this 
system being from *4o to $60 per acre. 
Under this system water is sometimes rented to others than stock- 
holders, the price being $12.50, equal to $1.25 per acre per year, 
which, considering the certainty of supply and the ability to use it at 
any time, is very reasonable.
