The data were compared with reconstructed streamflow records for each of the
streams which contribute to Overland Ditch and, on a month-to-month basis, the
smaller of the two values defined the water available for interbasin transfer. The
results of the preceding analyses are displayed in Table III-4.

The following tabulation is an abstract of Table III-4 and presents water that would
be available for development during a 4l;-year period, similar to the one studied
and under typical low, normal and high flow year existing conditions.

Amounts shown above represent the water available for development for the
portion of Tongue Creek basin considered only and do not include the portion of
return flows that are leaving the lower service area.

The water available for interbasin transfer, as calculated by the USBR, using the
Grand Mesa Canal would not be affected by any perfected conditional right. The
USBR studies analyzed water rights up to 1966. The Grand Mesa Canal holds a
conditional water right decree with an adjudication date of January 31, 1964.
Therefore, any decree or conditional right perfected since then would be junior to
the Grand Mesa Canal.
