PROPOSED FLOW-SHARING AGREEMENT:

1. When the diversion of 10 cfs of flow from the Blue River via the High-Miller Ditch
to the Oxbow/Floodplain Fish Habitat Improvements would reduce the flow of the
Blue River below the decreed ISF amount, after accounting for the average monthly
consumptive use flow rate from the Peabody No.1 Ditch water rights (the "Peabody
No. 1 Ditch Flow Rate Contribution") that are the subject of Case Nos. 05CW264
and 05CW265 that will be left in the river to supplement the CWCB' s 125 cfs
irrigation season (May through September) ISF, and a flow-sharing agreement shall
be implemented as follows:

a. All diversions to the designated off-channel oxbows that are part of the
Oxbow/Floodplain Fish Habitat Improvements shall cease during out-of-
priority periods when river flows are less than or equal to approximately 85%
of the existing ISF plus the Peabody No.1 Ditch Plow Rate Contribution for
the time period. As such, diversions to the Oxbow/Floodplain Fish Habitat
Improvements shall cease when the following thresholds offlow occur in the
Blue River:
