    Default Forester wading depth

    Anyone know what the maximum depth of water is that I can safely go through with
    my '01 S Turbo Forester? My route to work involves crossing a ford and on
    occasions it gets deep after heavy rain. Are there any known mods to increase
    the depth safely?

    Mouse over this picture to get a view of the ford when flooded.

    I went through it earlier last year when it looked quite deep and managed to get
    a wave up to the headlights. Unfortunately this ripped my front registration
    plate off and ever since then I have been more cautious.

    Ask around at www.ultimatesubaru.org .
    You may not need intake and exhaust mods - but IIRC the diffentials and
    transmission may need some special vent tube or something.

    "Each year, more deaths occur due to flooding than from any other severe
    weather related hazard. The main reason is people underestimate the
    force and power of water. More than half of all flood related deaths
    result from vehicles being swept downstream. Of these, many are
    preventable." - NOAA

    I strongly suggest you don't do this. Please see the NOAA web site "turn
    around don't drown":

    http://www.weather.gov/os/water/tadd/

    As a NOAA weather spotter (and Subaru Forrester owner *smile*) I've seen
    some film of just how little water it takes to sweep away a car and
    cause real harm to the occupents.

    As Carl said, the transmission, differentials, and I want to add wheel
    bearings. Should have no problems if the water is less than the ground
    clearance which is below the items above.

    This is as long as the flow does not sweep you away as the other poster
    noted.

    Of course the warnings about the force of moving water are important.
    The OP didn't mention whether the water was flowing or not.

    Flowing, but slowly, even in flood. I have seen plenty of small cars stuck in
    the centre of the ford up to the axles, but nobody has ever been swept away to
    my knowledge.

    If you become buoyant, it won't take much force to push you around. I
    would not push my Forester through more than a few inches of water.

    Here's some more specific information about how little water it takes to
    get into trouble:

    http://www.wvdhsem.gov/WV_Disaster_L...loodsandfloods
    ..htm

    And here's an amusing film for your viewing pleasure...I don't know if
    the driver made it out alive or not (so maybe not so amusing):

    I'll stop here as it's getting a bit off topic, though I think very
    important for those of us that drive "off road" capable vehicles.

    If I were to guess what is safe, I would say the 7 or so inches of
    ground clearance in the Forester. I don't know how water proof the
    chassis is but if submerged to that point, there will be more buoyancy
    and chance of being pushed with water flow.

    I learned my lesson a few years ago in taking my Forester through a
    field and driving through drifted snow. All 4 wheels were lifted off
    the ground and I had to dig snow from under and back out. You could do
    a calculation from weight of car and total bottom surface area, what psi
    would make it totally buoyant. Offhand ~ 0.25 psi or maybe chassis
    submerged in about 6 inches of water. Engineering type in group can
    comment.

    Also many years ago in a different car, I had the experience of water
    planing at about 50 mph. Truly scary when you have no control of car.

    I drive a 1999 Forester S, and have driven through a number of fords.
    My husband and I are both experienced off-road drivers. (He's an
    archaeologist, so it's part of the job for him, and I've been driving
    Subarus for over 20 years and love the back country.) I haven't seen
    many fords that ever get even close to axle depth in normal, non-storm
    conditions, and I wouldn't worry about water less than, say, eight
    inches deep. (That's around axle depth on our Forester.) The vehicle can
    handle it, even if the water is flowing fairly rapidly.

    Actual flooding conditions are completely different matter. They are
    *extremely* dangerous, not because of the depth of the water (which
    might be navigable when you check), but because that depth can change
    rapidly and without warning. We would *not* attempt to cross a wash or
    ford during a storm or when water levels are changing unpredictably,
    even if it was dry, except in a life-threatening emergency.

    I was in an actual flood once -- the 1995 Russian River flood in
    northern California. My Subaru almost got swept away when the water
    went up more than two *feet* in a period of perhaps thirty seconds.
    Fortunately I made it to the top of the next hill. I was driving on a
    low-lying road, not a ford or wash, but -- trust me -- you do *NOT* want
    to risk a similar experience.
