• 1.03 Project Conditions:

• Hydrographs of the St. Mary river and groundwater readings are provided in Section 51 00 10 and

51 00 70 to aid in the timing of construction and preparation for groundwater conditions.

• Contractor is responsible for the design, analysis, construction, and maintenance of the diversion system.

• The Government will be responsible for measuring flow and operating the existing headworks to maintain required flows through the system.

• 1.04 System Requirements:

• Temporary diversion system is required to convey canal flows from the existing headworks, around the work areas, and back into the existing canal.

• Diversion flows must be met with a minimum upstream water surface elevation of 4471.8 and a downstream water surface elevation in the canal of 4469.4. The locations of these elevations are shown on Drawing 15-D-60052.

• Temporary diversion system includes soil plugs. Construct soil plugs to maintain impervious barrier between diversion flows and dry work areas, and to maintain diversion flows. Contractor may elect for an alternative design for a water retaining feature where soil plugs are indicated on drawings.
