however, which they hare not considered is the amount of water 
which is stored in fact, but is supposed to be diverted for direct use. 
The private reservoirs especially practice storing their pro rata of 
ditch water when they do not need it for direct use. Man\ system- 
atically store water at nights and on Sundays, and in the aggregate 
this is no inconsiderable amount. The practice is indulged in very 
early in the season, as the reservoirs are empty and a general fear 
exists that they may not be entirely filled; later, when many of the 
reservoirs are full, this practice stops. For this reason the quantity 
stored during April and May is made larger than would at first thought 
seem proper. 
On the diagram will be noted small circles scattered over the por- 
tion representing the months of May, June, July, and August. These, 
with the year indicated, represent the highest water for these years. 
In the following descriptions of reservoirs those under each ditch 
are given together to enable one to form an estimate of the value of 
the reservoir and ditch as a system. The list contains many reservoirs 
of little importance, and these are inserted more with a view to mak- 
ing- the list complete than to their value. 
RESERVOIRS UNDER THE LOVELAND AND GREELEY CANAL. 
LAKE LOVELAND. 
This is the largest lake in the district, and one of the most noted in 
the State, not only for its size and capacity, but for the amount of 
land dependent upon it for water. The land irrigated has generall} T a 
ditch right, as well as reservoir right, reserving the latter until late in 
the season. 
The reservoir covers -±72 acres, and is located near the north bound- 
ary of the town of Loveland. It is a natural depression which was 
enlarged and improved by the building of a dike along the south side, 
18 feet high, 20 feet wide on top, with a slope of 3 to 1 on the inner 
face and 1£ to 1 on the outer face; the inner face is well riprapped 
with stone. A tunnel, lined with concrete, three-fourths of a mile 
long and 5 feet in diameter, furnishes ample outlet facilities and dis- 
charges into the Loveland and Greeley Canal. A brick tower near 
the south side of the lake at the upper end of the tunnel contains 
the mechanism for opening and closing the gates (PL III). The gate- 
are of iron sliding in grooves outside the tower and operated by a 
threaded rod. worm gear, and wheel. The amount discharged through 
the tunnel seldom exceeds 350 cubic feet per second. The inlet ditch, 
known as the Old Barnes Ditch, has its head gate 3^ miles above the 
reservoir, and a capacity of more than 400 cubic feet per second, though 
on account of the danger of breaking where it runs along a side hill, 
275 cubic feet per second is about the maximum carried.
