height="2.5736220472440943in"}A key element for effective irrigation
system design and management is an Irrigation Water Management (IWM)
Plan. The IWM Plan includes factors related to the irrigation system
including agronomic and management aspects. Irrigation water management
must be considered in irrigation system design to assure that the system
will supply crop water needs and function effectively and economically
as a

component of a production system. Likewise, for effective irrigation
system operation, an IWM Plan assists the irrigator or decision maker in
the management of the irrigation system and water application. The IWM
Plan should also provide guidance for appropriate record keeping of
irrigation activities and associated conservation measures.

**(a) [IWM Plan Components]{.underline}**

The IWM plan includes the following elements that meet specifications
listed in the Irrigation Water Management Job Sheet (449 OR-JS), and the
accompanying 449 OR-IWM Plan Worksheet (449 OR-IWM-Plan) provides a
format for developing an IWM Plan. These items are contained in Section
OR652.1005(c).

(1) Statement of Objective(s) for the IWM Plan

> Describe the principal objective(s) of IWM for the cooperator. Typical
> objectives may be to maximize crop yield and quality and to document
> water savings. Other objective(s) may include maximizing net return,
> frost protection, crop cooling, dust control, and other purposes. All
> pertinent objectives should be noted, including associated sub
> objectives and site-specific information that might influence IWM
> objectives.

(2) Irrigation System Description including Plan Map

# One or more conservation plan maps may be used along with narrative descriptions to describe the irrigation system. Components should be described including any limiting conditions that might affect system operations and water management. The IRRIGATION SYSTEM INVENTORY WORKSHEET (Section OR652.0907) can be used to obtain and organize information about existing systems.

> The following elements should be included in describing the irrigation
> system and its operation:

i.  Irrigation Water Supply:

<!-- -->
```
-   Supply flow rate (gpm or cfs) including seasonal variability.

-   Annual volume available (acre-ft).

-   Water delivery schedule including water rights and/or historical
    water use information.

    i.  Method of water measurement

    ii. Irrigation water conveyance:

```{=html}
<!-- -->
```
-   Description of water conveyance (pipeline, unlined ditch, lined
    ditch, etc.).

-   Methods of water control (valves, gates, etc.).

-   Water conveyance losses (% loss in conveyance).

    i.  Irrigation application:

```{=html}

-   System operation.

-   Factors affecting IWM.

-   On-site observations.

(3) Soils Information

    i.  Soils Map and Soil Description.

    ii. Soil physical properties affecting irrigation operations and
        water management:

        -   Available Water Holding Capacity throughout the soil
            profile.

-   Intake family characteristics and/or allowable sprinkler application
    rate.

-   Presence of any field-specific conditions and anomalies that may
    affect irrigation system operation including inhibiting or differing
    soil layers at depth, high water table, possible erosion and/or
    salinity problems.

(4) Crop Information

    i.  Crop(s) grown including expected crop mix and rotation.

    ii. Managed root zone as affected by maximum effective rooting depth
        and seasonal variation in rooting depth for each crop.

    iii. Management allowed deficit for each crop along with seasonal
         variations.

    iv. Crop consumptive water use (CU) including peak daily (design)
        CU, total seasonal use, and seasonal variation including
        planting and harvest dates for each crop.

(5) Description of Irrigation Scheduling and System Management

    i.  Net and gross application with corresponding frequency shall be
        identified for the design (peak water use) period for each crop
        grown (Refer to IRRIGATION WATER APPLICATION -- HOW MUCH, WHEN,
        SYSTEM CAPACITY WORKSHEET, Section OR652.0907.) This information
        should be related to the system capacity and water supply.

    ii. Description of system operation that corresponds to design (peak
        water use) period; e.g., hours per set and sets per day and days
        per cycle for periodic-move, solid-set, or microirrigation
        systems; cycle time for "continuous move" systems, and hours per
        set and sets per day and days per cycle for surface systems.

    iii. Guidance for seasonal adjustment of application depths and
         irrigation frequencies throughout the irrigation season.
         (Inefficient irrigations normally occur early and late in the
         irrigation season when crop water use rates are less than
         peak.)

    iv. A method for estimating crop consumptive use and rainfall shall
        be identified.

    v.  A method for monitoring soil moisture levels shall be identified
        and an appropriate method specified. (Assessing soil moisture
        provides opportunity to "calibrate" consumptive use and rainfall
        estimates, and account for errors in other estimates such as
        irrigation application efficiency. At a minimum, soil moisture
        assessment should include using the "feel and appearance" method
        but might also utilize soil moisture and/or plant monitoring
        instruments where appropriate.)

# Definition

Irrigation water management (IWM) is the process of determining and
controlling the volume, frequency, and application rate of irrigation
water in a planned, efficient manner.

# Purpose

IWM is applied as part of a conservation management system to support
one or more of the following:

-   Manage soil moisture to promote desired crop response

-   Optimize use of available water supplies

-   Minimize irrigation induced soil erosion

-   Decrease non-point source pollution of surface and groundwater
    resources

-   Manage salts in the crop root zone

-   Manage air, soil, or plant micro-climate.

# Where used

This practice is applicable to all irrigated lands.

An irrigation system adapted for site conditions (soil, slope, crop
grown, climate, water quantity and quality, etc.) must be available and
capable of applying irrigation water to meet the intended purpose(s).

# Conservation Management Systems

IWM is generally one of several components of a resource management
system used to manage water supplied to a crop through an irrigation
system that is

part of an overall resource management plan for the irrigated cropland.

**Irrigation Water Management Planning**

IWM components of the conservation plan will contain the following
information:

-   field map(s) and soil survey information

-   crop rotation or sequence

-   recommended irrigation water application rates, timing, and method
    of application

-   locations of designated sensitive areas

-   guidelines for irrigation system operation and maintenance

IWM is most effective when used in conjunction with other conservation
practices such as irrigation system design, cover crop, residue
management, conservation buffers, nutrient management, pest management,
and conservation crop rotation.

IWM requires knowledge, skills, and desire to determine when irrigation
water should be applied. The main factors influencing IWM are

-   ***irrigation interval*** (time between irrigations),

-   ***irrigation** **set** **time*** (time water is applied), and

-   ***application rate*** (rate at which water is applied).

These parameters define the timing and duration of irrigation and the
amount of water applied. System design and maintenance are also
important factors influencing IWM.

# Water Rights

Under Oregon law all water is publicly owned and anyone planning to
store or divert surface or groundwater for the purpose of irrigation
must obtain a permit or water right from the Oregon Water Resources
Department. These permits or water rights must be obtained prior to the
use of the water. It is the responsibility of the landowner to file for
the necessary permits or water rights. The landowner should complete a
*Producer Self-Certification of Irrigation History* (OREGON BULLETIN NO.
OR210-2007-2).

# Operation and maintenance

The operation and maintenance (O&M) aspects applicable to this standard
consist of evaluating available field soil moisture, crop
evapotranspiration rates and changes in soil intake rates and adjusting
the volume, application rate, and/or frequency of water application to
achieve the intended purpose(s). A review of the effectiveness of the
IWM Plan is useful in evaluating the effectiveness of the Plan and its
implementation.

####### Other necessary O&M items are addressed in the physical component standards considered companions to this standard such as Irrigation System and Irrigation Water Conveyance.

#######  **IWM Plan Specifications**

An IWM Plan shall be developed to assist the irrigator or decision-maker
in the proper management and application of irrigation water. Factors to
be included in the IWM Plan include the following:

-   Statement of objective(s) for the IWM Plan

-   Description of the irrigation system and its components including
    water supply, water conveyance and application systems, and any
    water measurement devices.

-   Soils information including available water capacity, depth, and
    limiting conditions related to irrigation water management.

-   Crop information including crops grown, irrigation water
    requirements, and physical characteristics including rooting depth.

-   Description of irrigation scheduling and system management including
    methods for measuring and/or estimating crop water use and soil
    moisture levels.

-   IWM record keeping requirements of appropriate detail for the IWM
    objectives. The detail of IWM may be specified as ***Detailed** or*
    ***By Irrigation Cycle*** with the associated level of record
    keeping as appropriate for the level of detail.

-   IWM review requirements regarding the effectiveness of the IWM Plan
    and its implementation.

####### **Worksheets**

IWM Worksheets and Record Sheets for developing an IWM Plan and
associated reporting are contained in the Oregon Supplements to Part
652, *Irrigation Guide*, Chapters 2, 9, and 10.

The Job Sheet and Worksheets are available as MS Word .doc files for
electronic fill-in. (The .doc files are "Read Only" so that they can be
edited but must be saved using a different file name.)

###### Basic SoilS & crop Information

Include all pertinent information about the soil(s) and crop(s),
including the presence of any field-specific conditions/anomalies that
may affect irrigation system operation such as inhibiting or differing
soil layers at depth, high water table, possible erosion or salinity
problems, etc.

Include information about crop rotations and crop characteristics that
may affect irrigation system operation and irrigation water management.

The following tables may be used, or include printouts of soil survey
data or soils and crop information documented elsewhere so that the
following pertinent information is contained in the IWM Plan. The
worksheet (OR IWM-9.2), ***[Irrigation Water Application -- How Much,
When, System Capacity]{.smallcaps}*** (Part 652, Section **OR652.0907)**
or a similar worksheet may be used and referenced.

Copy and complete individual tables if more than two major soils are
present and/or there is more than one crop rotation.

> Attach a soil survey map of the area of interest along with the
> following information:

-   Brief map unit description that contains the percent of area for
    each soil type when more than one soil type is present.

-   Soil physical properties including Available Water Holding Capacity
    throughout the soil profile.

-   Intake rate characteristics.

> (Refer to Part 652, Chapter 2 for soils guidelines and information.)
>
> Note any site specific conditions that affect irrigation system
> operation and management such as soil variability and anomalies,
> and/or conditions that affect irrigation system operations and
> management.

**Description of Irrigation Scheduling and System Management**

> Include worksheet(s) (hand- or computer-generated) that include
> irrigation system operations information including the following:

i.  Net and gross application with corresponding frequency for the
    design (peak water use) period for each crop grown. This information
    should be related to the irrigation system capacity.

ii. Description of system operation that corresponds to design (peak)
    period such as

-   hours per set and sets per day and days per cycle for periodic-move,
    solid-set sprinkler systems,

-   hours per day operation for micro irrigation systems;

-   cycle time for continuous-move systems, and

-   hours per set and sets per day and days per cycle for surface
    systems.

    i.  Guidance for seasonal adjustment of application depths and
        irrigation frequencies throughout the irrigation season.
        (Inefficient irrigations normally occur early and late in the
        irrigation season when crop water use rates are less than peak.)

> NOTE: The worksheet (OR IWM-9.2), ***[Irrigation Water Application --
> How Much, When, System Capacity]{.smallcaps}*** (Part 652, Section
> **OR652.0907)** or a similar worksheet may be used to develop the
> above information.

ii. Methods used for estimating actual consumptive use and rainfall.

iii. A method for monitoring soil moisture levels. (Assessing soil
     moisture provides opportunity to "calibrate" consumptive use and
     rainfall estimates, and account for errors in other estimates such
     as irrigation application efficiency. At a minimum, soil moisture
     assessment should include using the "feel and appearance" method
     but should include soil moisture and/or plant monitoring
     instruments where appropriate.)
