Going by this
Sodium hydroxide is extremely caustic, and can react with fats and oils on skin, in a reaction which creates salts. For this reason, sodium hydroxide is very dangerous, and skin should be washed thoroughly with water following contact with this substance.[citation needed]
A solution of 0.5M or more of sodium hydroxide should be labelled corrosive, while a solution between 0.5-0.05M should be labelled irritant.
I would guess that they could have lost 10 times that and had nothing more than localized damage at most

So the NaOH will react with the acid in the tannin, lowering the pH level and producing DMHO, causing the river to flow faster to release the excess? Well that's just great. If it's not one thing, it's another.
NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
Seriously though, while an inadvertent spill of anything is bad; I don't think this is worth losing any sleep over.
On a related note; this is the stuff to really watch out for:
