    WATER MANAGEMENT STRATEGIES MODULE

    Integrated Farm Water Planning Pilot Strategies

    Notes

    Resources

    5)Raise land

    If you can not relocate a building, raise the land to the flood plain elevation. Contact local government to discuss. Drainage Ref #7

    6) Build a dike/pump station

    Drainage Ref #7, 8, & 9

    Strategies to Address High Water Table 7) Upgrade downstream conditions to lower groundwater table

    The groundwater table may be higher due to water ponding downstream of your farm. Assess

    the downstream conditions to determine options.

    Consult with a Drainage Specialist. Drainage Ref # 7

    8) Maintain subsurface drainage

    Drainage Ref #7 & 10

    9) Install subsurface drainage

    Drainage Ref #7, 11 to 13

    10) Drainage Pump to lower water level & berming

    Drainage Ref #9

    Strategies to Address Local Flooding Issues11) Assess the capacity of the on-farm drainage system. Review how the on-farm drainage

    system is operating to understand if issues can be addressed with maintenance or if drainage upgrades are required.

    Consult with a drainage specialist, or complete a visual inspection during a storm event to look for issues. Drainage Ref #2

    12) Assess the capacity of the downstream drainage system. If the downstream system does not have capacity to pass storm events, the water may backwater onto your property. Assessment would review downstream channels, culverts and discharge

    locations. Assessment would determine if issues can be addressed with maintenance or if upgrades are required.

    Consult with a drainage specialist, or complete a visual inspection during a storm event to look for issues. Drainage Ref #213) Grade land to prevent ponding.

    Drainage Ref #7

    14) Maintain drainage ditches

    Drainage Ref #7 & 14

    15) Invasive species management
