Yes, as far as I know (unless maybe this was changed with some of the new stuff they have out now like WAA and whatever the bottom-bounce donut type deal that's mounted on the bottom of the Virginia class) determining exact depth has always been a problem.
I'd have to find it but one of the manuals for the Mk 37 torpedo basically says since you're probably not going to know your target's depth here's how to bracket with three staggered torpedoes, one shallow (60-300) , one medium (300-700) and one deep (700 and beyond).
My limited understanding of the matter though, when thermoclines are involved and the contact is localized, its usually enough to figure out "above or below the layer" and set the weapon for that approx depth (shallower or deeper than the layer) and let it do its work.
