Power Operation of Gates. Power operation is recommended for those gates
which require frequent operation or emergency operation. At those sites where
electric power is readily available, gates can be operated with electric motors
attached to the hoist. In general, these motors ore integral ports of the hoist and
may require replocement of the existing hoist. Electrically driven hoists should be
equipped with 0 torque-limiting device on the motor to prevent damage to the
motor, and should be capable of manual, as well as power, operation.

For those locations where permanent electric power is not available, it is
recommended that the hoists be set up for power operation using a portable power
unit. The recommended unit consists of a small gasoline engine which drives a
hydraulic pump, which in turn is connected to a hydraulic motor. The hydraulic
motor mounts directly on the hoist gearbox to operate the gote. The entire unit is
mounted on a small cart which can be easily transported in the back of a pickup
truck and handled by one man. It is proposed that each ditch rider have a unit for
his use in operation of the gates in his particular division, with a spare unit kept at
the Canal Company's office. It is assumed that all new or existing hoists (except
those with permanent electric operators) can be operated with this portable unit
with either minor or no modifications necessary.

4.3 Rehabilitation of Existing Structures and Facilities

This section of the report deals specifically with the work required to rehabilitate
the existing structures within the canal system. Construction of new facilities and work
related to specific topics (sedimentation, weed and trosh control, flow measurement, and
operation and maintenance) are discussed in subsequent sections. For the purposes of
this report, rehabilitation will be taken to meon, in general, the restoration of an existing
structure to its intended condition, and will not include improvements (new construction)
other than for safety.

Upper Diversion Dam, Fort Lyon Canal. This structure is located on the Arkansas
River approximately 3.5 miles upsteam from La Junta, Colorado, and allows water to be
diverted from the Arkansas River into a diversion channel which feeds the Fort Lyon
Canal. The structure is composed of a diversion dam across the Arkansas River with a
two-bay control structure near the left bank (see Figure 6 and Photograph I). There are
no provisions for regulating the diversion channel.

The overall condition of the structure is very good. There are no signs of extensive
concrete damage and the two steel radial gates appear to be in good condition with only
