Hi Nicole and Cheri,
Here is a link to five important documents concerning the Indio Subbasin and the ongoing groundwater
management efforts of CVWD and the other Indio Subbasin Groundwater Sustainability Agencies (GSAs). We
request that you download and include in the administrative record for the Coral Mountain Resort project, the
following five documents:
1. Coachella Valley RUWMP- 2021
2. CVWD Water Supply Assessment Fact Sheet
3. Indio-SGMA-Alternative Plan- Compiled- FINAL Adopted Dec. 2021
4. Indio-Subbasin Annual Report Workshop- March 22 Final
5. Indio-Subbasin WY- 2021 Final
https://www.dropbox.com/scl/fo/gcx5fvdyjg33zob3j6r4f/h?d1=0&rlkey=8abfyglm7yxyo67ykelvm0jyv
These documents contain important facts regarding some of the comments recently made by LRRD and other
members of the public regarding the sustainability of the Indio Subbasin, including:
(1) Since 2009, the amount of water stored in the subbasin has increased by approximately 840,000 acre-feet
through the groundwater management efforts of these GSAs despite the fact that the western United States
experienced extreme drought conditions between 2013 and 2016 that led to mandatory water use restrictions
and drastic cuts in deliveries of State Water Project water (see Indio Subbasin Plan Update page ES-4);
(2) Between 2020 and 2045, the amount of groundwater in the Indio Subbasin is expected to increase further,
even after accounting for the Coral Mountain Resort project and all other existing users and planned future
growth in the Coachella Valley, and after accounting for the effects of climate change and further extreme
drought conditions, as well as planned groundwater management efforts (see Indio Subbasin Plan Update
page ES-12 and Figure ES-8);
(3) The Indio Subbasin SGMA Alternative Plan Update does not assume that more water will be delivered to
California in future years, but rather, takes into account that through existing water transfer agreements,
slightly more of the Colorado River water delivered to California will be allocated to CVWD (see Indio Subbasin
Update pages 6-8 — 6-10 and Table 6-3); and
(4) This Alternative Plan Update also assumes the worst case scenario under the Colorado River Lower Basin
Drought Contingency Plan, whereby CVWD will be required to contribute a portion of its allocated Colorado
River water so it will remain in Lake Mead; and assumes that only 45% of the State Water Project allocation
will be delivered, which is more conservative than the assumptions made by the California Department of
Water Resources (see Indio Subbasin Update pages 7-43 — 7-44).
