Good info!!
I've always been, and still am, skeptical of dowsing rods, but that's how the old timer who dug my well did it. He said we had water at 20' , but went down to 100'.
As well as you should! They ain't gonna pay for that fiber that you just dug through.Not knocking anybody that's posted above. I have been in excavation for a lot of years. And anytime I'm around someone that mentions they can "witch" a line or utility or anything for that matter. I trust all of about 0% what they say from then on out

This ^^^. That is why most states require a minimum of an 18-foot sanitary surface seal on water wells.I can witch buried utilities with a pair of copper rods. It is surprisingly accurate for me. Hold the rods straight out and when you cross something buried, they will pull together and cross. I haven't tried to divine water though. For those that do dig shallow wells, be aware that you are probably hitting water that is known as a GUDI. (Groundwater under direct influence of surface water). I would not consume it without testing it first.
I never trusted the locate marks made by professionals either.Not knocking anybody that's posted above. I have been in excavation for a lot of years.

Yep, airports are bad. Schools are also horrible for unknown/unmarked utilities. We would hire a third party locator for these sites because asbuilts were not kept up to date and volunteer projects were never documented. As far as USA dig is concerned, they do have a margin of error and when close hand digging or hydrovac is the safe route for sure. Worked on a four year hospital project several years ago, by contract ALL Sensitive U/G utilities were to be located by either hand digging or hydrovac. Med gases, com lines, power, chiller, h2o and so on .....I never trusted the locate marks made by professionals either.
1 they never locate abandoned lines and 2 they are less than perfect.
Asbuilt paperwork is never a 100% either.
Boss hit a chilling line for the airport in the twin cities put a tooth thru a ductile iron pipe locates were off more than the 2’.
i found a fiber optic line unmarked at the north end of the airport by Mother Lake digging with a tractor hoe. Found countless abandoned lines cuz everywhere you dig at the airport there is something.
