shou ld be reviewed for accuracy. The limitations of the existing data are also related
to the limitations of the data records produced and maintained by these small
municipalities which are typically short - staffed and budget - limited. In addition, local
water planning can be compromised by the complexity of Colorado water law. Recent
experience has indicated that the water rights portfolios of some small municipalities
may have incompatible uses (agricultural vs. domestic) and/or may not provide the
long term domestic water supply security as was believed (e.g., Cedaredge, Orchard
City, Hotchkiss). Limitations on supply should be investigated based upon an
analysis of historical minimum supply conditions (e.g., during the drought of 2002 –
2004).
To review the accuracy of the data, the Consultant will develop a list of communities
to contact and will finalize this list with the Gunnison Basin needs assessment
subcommittee. After finalizing the list of communities the Consultant will contact the
communities to g ather this information.
Deliverable: D raft and final technical memorandums describing the results of the
information from the smaller communities.
2) Basin - wide – Review and refine the estimate of current and future rural domestic
demands and supply in the Gunnison Basin.
The Consultant will investigate many areas of the Gunnison Basin with respect to
rural domestic water demand and most likely under represented these water
demands. In particular, it is believed that many headwaters areas (including, but not
limited to, Upper Gunnison sub - basins of Ohio Creek, Tomichi Creek, Cebolla Creek,
and Lake Fork, the North Fork sub - basins of Anthracite, Hubbard, Muddy, Terror,
Leroux, Smith Fork, and Minnesota Creek, the Upper Uncompahgre sub - basins of
Dallas and Cow Creeks, and sub - basins of Surface Creek) are not accurately depicted
with respect to these demands. In most cases, rural users have access to a physical
supply of water through wells or small creeks. However, now that the Gunnison
River Basin has bee n deemed over - appropriated by the Division of Water Resources,
many users will need to develop sources of augmentation to provide legal protection
against downstream senior water rights year - round. Although the current rural
demand for augmentation water is estimated to be relatively small, there are many
domestic water users that are at risk of being out of priority and curtailed. In addition,
an assessment is needed to quantify the future demand for augmentation water
storage in headwaters areas as growt h pressures continue and more rural
subdivisions are developed in the basin. Limitations on supply should be
investigated based upon an analysis of historical minimum supply conditions (e.g.,
during the drought of 2002 – 2004).
Based on funding constraint s, Task 2 will not fully be completed but elements will be
discussed with the needs assessment subcommittee to further refine the elements to
be completed under this task.
