"(2) Any water stored in Chatfield Reservoir for pur-
poses of f190d control should be released therefrom as
rapidly as possible without thereby exceeding the safe
carrying capacity of the downstream channel in order to
avoid disturbing the existing diversions and uses of water
in downstream water districts or interfering with estab-
lished priority rights under which such diversions from
the South Platte rtiver are made. The outlets from Chat-
field Reservoir Sh~lld, if necessity requires, be sub~ct
to closure to whatever extent may be needed to enable the
channel below the reservoir to accommodate floods arriving
from uncontrolled drainage areas dovmstream."

Paragraph (2) under the heading "Recommendations of the l3oard--

"( 2) Chatfield Reservoir be designed and operated ex-
ClUSively for flood control purposes, and may be included
in the plan of improvement, recommended by the District
Engineer for authorization together with the four projects
for flood control, and other purposes listed at page 119,
paragraph (a) of the report."

Royce J. Tipton, Consulting Engineer of the Board, and representatives
of the Corps of Army Engineers and the Bureau of Reclamation further explained
the reasons why both the Army Engineers and the Bureau had requested the Board
to reconsider its comments so as to approve plans and designs for the Chatfield
Reservoir to provide, in addition to flood control, conservation capacity. It
appeared from the resolutions adopted at public hearings on the matter, herein-
above mentioned, revision of such official state comments as approved by the
local affected interests, subject to certain conditions, should be made.

After discussing the matter and considering. the reso-
lutions passed at the hearings on the matter, it waS moved
by Judge Dan Hughes aDd seconded by Teller Ammons' that the
official State comments of July 12, 1945 on the South Platte
Flood Control project be revised as follows:

I

raragraph (1) (a), Page 2, and Paragra]il (2') under the
heading "Recommendations of the Board", Page 4, be so altered
as to withdraw objections to conservation storage in Chatfield
Reservoir, a feature of the South Platte i'lood Control proj-'
ect, in connection with flood control capacity through exchange
which may be provided by facilities that later may be made avail-
able at the Two Forks site upstream from Chatfield; provided
(a) that existing diversions and uses of water and established
priority rights under which diversions from the South Platte
are made shall not be disturbed by project operation; (b) that
such provision for conservation capacity shall not decrease the
amount of usable water available for the above-mentioned exist-
ing and established water rights by reason of evaporation losses
