I was looking at the VFR sectional near Thousand Oaks, California. The chart has a "WATER TANK" labeled, but I see many water tanks in Thousand Oaks on the Google Maps satellite view.

Does anyone know which water tank they are referring to on the sectional? And why would they choose something so easily confused with other "water tanks"?

  • $\begingroup$ Google seems to match VPLWT with some coordinate. Does it match any actual water tank? $\endgroup$ – vasin1987 Feb 10 at 10:06

The tank is west of Oak Park (Oak Park Canyon), but there is some conflicting information about the exact coordinates of VPLWT.

From FAA JO 7350.8P:

34-10-49.0000N 118-46-16.0000W.

Converted into decimal degrees: 34.18028°N 118.7711°W

Obviously no tank here!

As @ymb pointed out, this document has been cancelled, and in the current version (JO 7350.9N), the coordinates have changed:

34-11-01.0000N 118-46-41.0000W.

Converted into decimal degrees: 34.18361°N 118.7781°W

An underground tank, well visible from the sky. The tank itself is likely similar to this (it may be it, but not sure):

"Local officials recently toured and inspected the new Oak Canyon water tank under construction in Oak Park", source

Other tanks

There are also two external tanks in the neighborhood, but none corresponds to FAA coordinates, e.g. this one:

which is a bit north of the underground tank. Overall picture:

It seems FAA has not done a good job about this waypoint identification. While the current source identifies a tank, it should be mentioned this tank is underground, as this makes a difference.

I would say this one, north of the 101 on Savoy Ct

  • $\begingroup$ FAA says VPLWT is at 34-11-01.0000N 118-46-41.0000W faa.gov/air_traffic/flight_info/aeronav/aero_data/Loc_ID_Search/… which google maps shows is not close at all: 34.110100 -118.464100 Draw a line Northwest from Agoura Hills, and another Northeast from the lake with all the fingers, and their intersection is pretty near the tower I suggested. google.com/maps/place/Thousand+Oaks,+CA/… $\endgroup$ – CrossRoads Feb 10 at 23:52

    $\begingroup$ Sorry I dont have calculation done but 34-11-01.0000 is definitely not equal to 34.110100. Faa notation is some degree and arc of degree. You need some conversion to make it decimal. $\endgroup$ – vasin1987 Feb 11 at 5:00
