OPERATION

This section provides instruction
s

for the d
am operator during normal operations. An
O
perating
L
og
, found in Appendix A
-
4,

shall be maintained by
(Insert organization name)
. This log shall
indicate the beginning and ending date of all
storms causing the auxiliary
(emergency)
spillway
to operate,

any

problems encountered, and any other pertinent data or observations.

Normal Operation

Normal operation is defined as any time: 1) the dam is dry

or

2) a storm is occurring that will not
cause flow through the auxiliary spillway. The
structure does not
have a gate and has no
operational mechanisms.

(This paragraph may be adjusted and modified to explain actual and/or
additional features of the dam’s operation)


Insert
D

is designed to temporarily retain floodwater,
store sediment
and discharge all

floodwater within
____

hours.
As sediment accumulates in the reservoir,
maintenance actions
will be needed to prevent sediment from exiting through the principal spillway and to preserve
the lifespan of the sediment storage area of the reservoir.
(Explain

here in detail the maintenance
operations
, such as closure of riser ports,

to be taken to prevent and/or reduce sediment
movement through the principal spillway and explain
planned
sediment removal operations to
maintain the sediment storage capacity of t
he reservoir area.)


Emergency
Action Plan

Emergency operation of
Insert
D
am
N
ame


occurs when
unusual events such as
1) the dam may
be overtopped, 2) a storm is occurring that will cause flow through the auxiliary
(emergency)
spillway, or 3) rapid
deterioration of the dam is occurring.

During these situations, the dam
operator must closely
monitor the dam
and activate the Emergency Action Plan

(EAP)
.

The
Emergency Action Plan is a separate document that identifies potential emergency conditions at
the dam and specifies preplanned actions to be followed to minimize property damage and loss
of life. The dam owner and operator must be familiar with the details in the Emergency Action
Plan.


INSTRUMENTATION AND
MONITORING

Insert dam name

does not have
any type of instrumentation. The structure
must
, however, be
visually inspected on a periodic basis to identify potential problems.
(If dam has instrumentation

or periodic settlement surveys are needed
, explain
these
system
s

in detail here)


INSPECTION
S

A
representative of
(Insert organization name)

shall perform routine inspections to ensure timely
identification of potential problems.
(The title of the person tasked with conducting the following
inspections may be listed if
available
)
Inspections will be
performed
__________

(

duties.

If abnormal
conditions are observed, then a special
or annual
inspection must be scheduled.


2.

Special

inspections will be conducted immediately followi
ng severe storms,

earthquakes,
initial filling of the reservoir, vandalism, and other significant events.

The

inspection
checklist
located in Appendix A
-
1

of this manual must be used.
A severe storm is defined
as one where the depth of flow discharging fro
m the principal spillway conduit is
___

inches.
(A specific depth of rainfall over the watershed or at the dam location may also be
used to define the severe storm.

3.

Annual

inspections will be accomplished
during the non
-
flood season

by
trained
personnel of the
(Insert organization name)

using
the

inspection checklist
located in
Appendix A
-

of this manual.
For the first 3 years after

installation of the structure, an
NRCS engineer shall participate in the annual

inspections.

(The last se
ntence may be
eliminated and/or
adjusted as appropriate

to meet any NRCS agreement requirements.
)

4.

Formal

inspections shall be conducted at least once every 5 years. These inspections

are
to be accomplished under the
direction

of a registered professiona
l engineer

licensed in
the State
of New Mexico
and qualified in the design and construction of dams
. The
purpose of the

inspection is to
perform a detailed inspection and engineering evaluation
of the dam and appurt
en
ances.

The individual conducting
any

in
spection must record all pertinent observations and data. A
photographic record of inspections, with locations and dates of photos, can assist in diagnosing
and solving problems that may arise. The inspection report and photos shall be placed in the
O
perat
ing
L
og, which is maintained by
(Insert organization name)

and
made
available to other

parties

as
deemed

appropriate

by the dam owners.

A copy of the Special, Annual and Formal
inspection reports shall be provided to the OSE Dam Safety Bureau.

Preparing a
n inspection route in advance helps assure that every part of the structure will be
observed. The following is a recommended sequence for an annual inspection

of the main
earthen embankment structure
.




Crest

-

Walk
along

the crest from abutment to abutment.



Downstream Toe

-

Walk the entire length of the downstream toe.



Upstream/Downstream Slope

-

Walk across the slope
from abutment to abutment
in a

pattern such that the entire slope is inspected.



Principal Spillway and

Outlet Conduit

-

Observe all accessible features of the
principal
spillway
.



Auxiliary
(Emergency)
Spillway

-

Walk along the entire length of the spillway in a back
and forth manner.



Embankment
-
Abutment Contacts

-

Walk the entire length of the embankment
-
abutment contacts (groins).



Abutments

-

Traverse abutments in a practical manner so as to gain a general feel for the
conditions that exist along the valley sidewalls.



Downstream Channel

-

Travel the route of the stream below the dam to maintain
familia
rity with locations of residences and property that can be affected by dam failure.



Reservoir Slopes

-

Scout the reservoir perimeter in an effort to develop an overall
familiarity with its conditions.



Additional items may be added as deemed necessary

Ins
pection of the outlet channel is completed by traveling along the channel and observing and
recording locations of erosion, sedimentation, or debris.
