In Nonnenbach countless dead fish remained: Strömer, minnows and brook trout - former were on the red list of fish species in Baden -Württemberg - were obliterated, decimated grayling, sculpin and other fish species.

The Nonnenbach in the literature

Bends of the nuns Bach he saw deep beneath the corner wood, litter meadows, alder. What a dark quiet places caused by the fact that the brook the shore in places wegfrißt, but it then has to stand at the next alder group again. Behind the root of such associations alder pulpits arise pure dark mirror. (...) Xaver was as a child, often for days on Nonnenbach down there and had bent most like about the quiet dark places in the creek bends. Had the arm into stretched and let him break from the water table.

And in the 1998's novel A gushing fountain

Hengnau ... and after going hamlet there are no more than three kilometers. A straight line. In reality, it goes behind Hengnau quite uphill, then through the forest Atzenbohl - deep down to Nonnenbach, on the Crooked bridge over and immediately quite steeply up to the hamlet, whose name is going hamlet.

And in his novel The Unicorn from 1966:

Tough ..., Anselm said, winds, as you can see, punctuated by too many alders, the Nonnenbach his silent story through the valley down.
