OPERATION
This section provides instructions for the dam operator during normal operations. An Operating
Log, 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 Dam Name 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 the reservoir area.)
Emergency Action Plan
Emergency operation of Insert Dam Name 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 systems in detail here)
INSPECTIONS
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 __________ (Insert time
frame, weekly, monthly, etc.) and annually during the non-flood season, which allows needed
work to be completed before summer thunderstorms. Four types of inspections are required to
ensure that the flood control structure functions as designed.
(Insert Dam Name Here), O&M Manual
Insert Date Here
-5-
1. Monitoring inspections of the dam will be accomplished ________ (Insert time frame,
weekly, monthly, etc.) to identify and report abnormal conditions between the other three
types of inspections. Trained personnel of the (Insert organization name) will perform the
monitoring while carrying out operational and maintenance duties. If abnormal
conditions are observed, then a special or annual inspection must be scheduled.
2. Special inspections will be conducted immediately following 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 from 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-1 of this manual. For the first 3 years after installation of the structure, an
NRCS engineer shall participate in the annual inspections. (The last sentence 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 professional 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 appurtenances.
The individual conducting any inspection 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
Operating Log, 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 an 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 embankmentabutment 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
familiarity 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
Inspection of the outlet channel is completed by traveling along the channel and observing and
recording locations of erosion, sedimentation, or debris. Table 1 provides specific items and

1. Perform a detailed annual inspection of all project elements using the checklist in Appendix A-1.
2. Inspect earthen embankments for erosion, rills, cracks and rodent burrows.
3. Inspect earthen embankments, outlet channels, and all concrete
structures for woody vegetation, tree seedlings, trees and large shrubs.
4. Inspect all concrete elements, including interior of riser for cracks, spalling, loss of joint filler or sealer, and
other signs of deterioration.
6. Check fences, gates, and related appurtenances for signs of disrepair.
7. Check for corrosion on all exposed metalwork.
8. Inspect reservoir pool, outlet channels, inlet structures, and any other area that may result in debris
blockage or debris being transported to or through the floodwater retarding structures or outlet channels.
9. Review and update emergency action plan.
MAINTENANCE
Preventive maintenance will be performed on Insert dam name and its appurtenances to ensure
the safe function of the dam. Representatives of (Insert organization name) will execute routine

PERSONNEL SAFETY AND TRAINING
Safety of operation and maintenance personnel is of the utmost importance to the owners of this
flood control dam. The objectives of our safety program are to establish acceptable standards
that identify major potential hazards and to minimize the risk of personal injury and loss of life
to maintenance personnel.
The major safety areas of concern are:



Operation of maintenance machinery, both hand held and mechanized
Application of pesticides and herbicides
Operation and inspection within confined spaces
The following guidelines outline the procedures that will be followed to meet these items of
concern and are intended to complement current OSHA and State of New Mexico regulations
regarding employee safety and health and are not intended to supersede any federal or state
safety regulations or the regulations of any particular dam owner. (OSHA Small Business
Manual, located in Appendix B-5, can be used as a reference for additional safety guidelines, if
needed. Refer to dam owner’s adopted safety manual/policy, if applicable)
