Record rush to secure bit of gold in stream maybe (9)

Ross

I believe the answer is:

discharge

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

'secure bit of gold in stream maybe' is the definition.
I can't judge whether this defines the answer.

'record rush' is the wordplay.
'record' becomes 'dis' (I can't justify this - if you can you should give a lot more credence to this answer).
'rush' becomes 'charge' (charging is a kind of rushing).
'dis'+'charge'='DISCHARGE'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for discharge that I've seen before include "empty" , "Performance" , "Send away - perform" , "Dismiss (from a job)" , "Put out" .)
