When the sluice is first opened, the water that pours through is beautifully clear, and slightly green in colour, like the water of a brook; this is the upper layer, which, carried along by its weight, is the first to appear. By degrees the water becomes less transparent, and takes on a greyish hue; this is the second layer, emptying itself in turn, and every now and then, more frequently as the water becomes muddier, a ray of silver is seen to dart through it; it is some fish, too small and weak to resist the current, which flashes past as if acting as scout for its stronger brethren. Nobody troubles to pick it up; it is allowed to lie gasping, and trying to find some little stagnant puddle of water at the bottom of the pond, flapping, floundering and capering like an acrobat going through his antics.
Then the black water comes pouring through; this is the last act, the final catastrophe.
Each fish, according to its power of resistance, struggles against the current which is bearing it along in this unusual manner. Instinctively they feel there is danger, and each strives its hardest to swim in an opposite direction; the pike struggles beside the carp which it was yesterday pursuing so hard; the perch is reconciled to the tench, and as they swim side by side, does not so much as think of taking a bite out of the flesh he finds so palatable at other times.
