The Soil Conservation Service evaluated three alternative plans:

1. Future conditions without project

2. Improved water management with minimwn works of improvement

3. National Economic Development Plan (NED)

Tole I.~LD clan was selected as the Soil Conser-vation Service Rec01t1mended Plan

and the farmer selected plan. Al though local interests have expressed their

preference for this plan the cost sharing requirements presents obstacles for

many farmers to implement these improvements.

Comb ined Plan

In order to alleviate the cost to the local farmers the SCS and Reclamation

have explored the possibility of building a pressurized sprinkler irrigation

system. Under this plan Reclamation would build the main distribution system

and the SCS would be responsible for the on-farm sprinkler systems.

The incremental cost associated with developing the plan is presented in

Table 1.

If the combined plan were to be buil t. this would preclude the construction of

any independent plans by SCS and Reclamation.

Under Reclamation's plan of winter watering, stock ponds would be lined and

enlarged to eliminate the need for running water through canals during the

winter months. Under the comb ined pI an. wate r for I ivestock would be del i-

vered through the main distribution system to stock watering troughs.
