probably dow equal to ite decreed priority, but it could ho enlarged to 
hold at leasl one-third more than that amount. The Lone Tree Lake 
has a capacity of nearly twice that of the Mariano Lake. Being high 
enough to irrigate most of the lands under the ditch, it does not 
exchange water with the river. Such lands as lie above it are sup- 
plied by that taken in exchange for the Mariano Lake water. 
The following lesser reservoirs are also under or supplied by the 
I Ionic Supply Ditch: 
The Rist Reservoir, supplied like Mariano Lake, from the Rist Ditch. 
covers some 40 acres, and is used to irrigate the lands of the Buck- 
ingham estate, to which it belongs. It has a capacity of 1 L5 acre-feet. 
The Big Hollow Reservoir, a seepage reservoir in sec. 27, T. 5 N.. 
lv. 68 W.. has a capacity of 30 acre-feet. 
The Allen Reservoir, 6 acres in area, in sec. 6, T. 4 N., R. 07 W., is 
also a seepage reservoir, with a capacity of about 85 acre-feet, which 
may be increased. 
The White-Butler Reservoir, on the south side of the Little Thomp- 
son, has purchased rights from the Home Supply Ditch, Imt it is not 
properly in the Big Thompson district. 
There is also one other reservoir on the south side of the Little 
Thompson, but it is supplied by the Hillsboro Ditch: name unknown. 
It has an area of 160 acres and has a capacity of 1.500 acre-feet. 
DUTY OF WATER. 
The data at hand scarcely justifies discussing at any great length 
the duty of water. To reach results of value would require an exami- 
nation and classification of the soil under each ditch, the kind of crops 
raised, and measurement of the water used by each over a series of 
years. The following table gives, however, such data as has been 
collected:
