Think you're unlikely to find any in the latter habitat. Seems to be a lowland species which in the south-east is found around lakes/large ponds with good amounts of reeds or similar emergent vegetation; even wide channels between reeds. I've found them locally in the last couple of weeks where I wasn't aware they occurred- one of the upsides to the lockdown!
Basingstoke Canal is one of the good places to look round here and although they do venture into the centre their patrol lines tend to be up and down the reedy/rushy banks for the most part.
