SUM OF FUTURE & EXISTING UNDECREED USES
Another method to estimate the maximum amount of future uses is to base what will happen in
the future on past uses. The existing uses deplete about 20,000 AF of the average annual natural
river flow; therefore, assume the future uses will be no more th n� AF.

Durango has offered
2,000 AF Diversion for no more
than 20 yrs, then no further
allowance.
With as much depletion as
possible from the uses, e.g.
domestic would be 350 AF
RICD would control an average of 159,000 AF per year or 27% of the flow.
Another method to estimate the maximum amount of future uses is to base what will happen in
the future on past uses. The existing uses deplete about 20,000 AF of the average annual natural
river flow; therefore, assume the future uses will be no more th n� AF.
