Dam through the Gunnison Tunnel and the South Canal to the
Uncompahgre River.

To distribute the waters of the Gunnison and Uncompahgre Rivers, the
South and West Canals were constructed. Some of the larger existing
private canals that take water directly from the Uncompahgre River
were purchased and then enlarged and extended. Laterals were
constructed to deliver water from the South Canal to project lands.

Principal project features are shown on Figure B.2 and are described
as follows:

Taylor Park Dam and Reservoir. Taylor Park Dam is on the Taylor
River, a tributary of the Gunnison River. The dam is a zoned
earthfil1 structure 206 ft high, with a crest length of 675 ft and a
volume of 1,115,000 cubic yards. It creates a reservoir with a
storage capacity of 106,200 af. The spillway is an overflow type
with a crest length of 180 ft and a capacity of 10,000 cubic yards.
The outlet works consist of a horseshoe shaped tunnel with a
diameter of 10 ft, and a capacity of 1500 cfs.

Gunnison Diversion Dam. Tunnel. and Canal System. The Gunnison
Diversion Dam on the Gunnison River, about 12 miles east of
Montrose, is a timber-crib weir with concrete wings and a removable
crest. The dam has a structural height of 16 ft. It di verts
Gunnison River direct flows, as well as releases from the Taylor
,Park Dam, into the Gunn1'son;Tunnel. "

and 12 ft high, with an arch shaped roof. A number of modifications
have been made since the original construction. It is 5.8 miles
long and tests performed in the spring of 1987 confirmed a maximum
capacity of 1135 cfs.
