Fishing for brown trout 

Lifeguard slang for seiving turds out of a swimming pool. This is usually done after clearing the pool, followed by a 1 hour break from pool use while you 'shock' the pool (i.e. dump a ton of chemicals into it and the run the filters at full blast).

I had to go fishing for brown trout today during the 'mother and baby' swim lessons. At least I got paid for an hour of playing computer games while the filters did their thing.
