I believe the answer is:

niagara

I'm a little stuck... Click here to teach me more about this clue!

'wet location' is the definition.
The definition suggests a singular noun which matches the answer.

'i rang aa when sloshed' is the wordplay.
'when sloshed' indicates an anagram.
'i'+'rang'+'aa'='irangaa'
'irangaa' with letters rearranged gives 'NIAGARA'.

'in' is the link.

Can you help me to learn more?

(Other definitions for niagara that I've seen before include "US/Canadian falls" , "North American waterfall" , "Famous waterfalls" , "Canadian waterfall" , "N. American waterfall" .)
