Reservoir. The following regulation will govern releases from
Pueblo Oam and Reservoir.

(1) The water control dia(\ram showing the sensonal
conservation pool is presented as Exhibit "E."

(2) When the reservoir level is at or below the top
of seasonal conservation pool and flooding is predicted not to
exceed the seasonal conservation pool, releases will be governed
by the Colorado State Engineer. The outflow will be maintained
in a manner to not exceed a flow of 5.000 c.f.s. at the Avondale
gage on the Arkansas River.

(3) When the reservoir level is at or below the top
of seasonal conservation pool and is predicted to exceed the season-
al conservation pool, regulated releases may be made in amounts
which, when combined with local inflow below the dam, shall not
contribute to flows in excess of the channel capacity at the
Avondale gage on the Arkansas River (5,000 c.f.s.).

(4) When the reservoir level is above the top of the
seasonal conservation pool, the regulated releases shall be mad"
at the maximWll rate permissible but limited to an amount which
shall not produce flows at the Avondale gage in exceSs of 5,000 C. Lll.

(5) When the reservoir level rises above elevation
4898.7 feet mal (spillway crest elevation), conduit releases should
not be made except to insure the safety of the structure.

b. Emergency Regulations for Flood Control. Should
communications be disrupted with the Albuquerque District Office
and/or the Project Manager's Office the Uam Superintendent will
direct regulation of the reservoir in accordance with the follo...ing
rules of regulation until communications are restored. In addition,
the Dam Superintendent will immediately make every effort to
reestablish communications.

(l) The water control diagram showing the seasonal con~er-
vation pool is presented as Exhibit "E."

(c) When the pool elevation is below the top of
seasonal conservation pool flood releases shall not be made throul~h
the outlet works. (When communications are restored, the Colorado
State Engineer will direct release. of the stored wnter.)

(3) \Jhen the pool elevation is in the flood cont rol
pool between seasonal conservation pool and elevation 439B.7 feet
