Weather for fish but what about otters?

It’s on days like these that you’d be hard-pressed to recall the ‘limpid silver glide… Between emerald banks’ of poet David Gray’s Luggie. Have you seen it? The water’s high and foamy and you might rather imagine his ‘pellucid’ waters turned to fast-gushing stout, complete with creamy, frothing head. Doubtless it would be fine for those who enjoy white-water rafting. But how do otters get on when it’s been raining hard, and mud (and branches) are being whipped along by the current? Does anyone know? It must be really hard to catch fish. (From Drowned Rat)
