Skalský rybník, Natural monument and protected area in Skály, Czech Republic.

Skalský rybník is a pond that forms the core of the Skalský rybník a Klokočínská olšina nature monument, covering 12.82 hectares northeast of Skály in the Písek district. The monument includes the pond, its banks and the wooded growth below the dam, with an inner zone marked by two red stripes.

The protected area was declared on 4 December 1985 by the Písek district national committee, with effect from 1 February 1986. It takes its name from the pond that occupies a substantial part of the site. In spring 2008 the pond was partly drained.

The name comes from the village of Skály and from the rybník, the fishpond that occupies most of the site; the second part of the protected area's name refers to the alder stand below the dam. The pond is managed for nature conservation, not for recreation, and the area is a natural monument.

The protected area lies 1.5 km east of Skály between railway lines 190 (Protivín–Strakonice) and 200 (Protivín–Písek). The core is marked with two red stripes, and a buffer zone of 140 m to the northeast and 50 m elsewhere surrounds it. The pond was partly drained in spring 2008.

The pond's fish-rich shallows once drew ospreys, a species recorded here in the past. Today the surrounding meadows host black-tailed godwits and redshanks, while the reserve's inner boundary is marked by two red stripes on the trees.
