extended from 6:00 a.m. to midnight.

Instream Flow Water Rights

The CWCB instream flow water rights database indicates no instream flow water
rights along the Animas River mainstem. As a result, the Durango Boating Park will not
have any impact on existing instream flow water rights.

Administration

The proposed RICD water right can be administered through use of the existing
Animas River at Durango gaging station together with a new staff gage to be installed on
Lightner Creek. The available flow to meet a potential call of the RICD would be equal
to the measured streamflow at the gage locations. The RICD water right is reasonably
capable of being administered by the Water Commissioner through the use of these
gage measurements, and calls by the RICD can be administered just like calls for any
other water right. It is noted that the water courts in other water divisions have
determined similar boating park water rights to be capable of administration.
