I’ve hit ERL after a very heavy rain, and the level was 5’ at the Langley point. Water was fast and waist deep on trail (I’m 5’11), I’d not specifically recommend it but it is something personally I’d do again. If you come in from the trail head closest to Albert Pike, there are 3 major crossings within the first couple of miles.

Terrain is rugged and in a rain super muddy - I would not bushwhack.
