Do you mean reeds (Phragmites australis) or one of the other big
marginal grasses - reed canary grass (Phragmites arundinaceus) or reed
sweet grass (Glyceria maxima)? Reed canary grass is the one that more
commonly grows on land as well as at the water's edge.

in general nothing over an inch survives constant mowing, but selective
weedkiller might work as well


You'd be hard pressed to find a weedkiller that killed reeds and not
other grasses. And using weedkiller near streams is not generally a good
idea.
