Kerské rybníčky, Natural monument in Kersko, Czech Republic.

Kerské rybníčky is a set of three shallow forest ponds in Kerský les between Velenka and Třebestovice near Sadská, at 191–199 m above sea level. The 9.23-hectare natural monument, declared by Central Bohemian Region regulation 6/2011 effective 13 August 2011, lies on Středolabská tabule over limestone, sandy marl, sand and loam.

In the Middle Ages a pond stood in Kersko Forest and gradually dried up. Because the groundwater level stayed too high, Josef Hyross drained the forest, and the three shallow ponds were dug for that purpose. The site was declared a natural monument by Central Bohemian Region regulation 6/2011, effective 13 August 2011.

The protected area integrates with the Bohumil Hrabal Nature Trail, established in 2014, featuring 13 information stations throughout Kersko Natural Park.

The site is easily accessible via well-maintained forest trails that wind through the area. Nearby you will find the Saint Joseph Spring, which offers mineral water and works well as a stop during your visit.

The great crested newt population here has declined since the mid-20th century, and conservation now depends on stopping fish stocking and thinning shading trees so sunlight warms the water. The site was declared a natural monument by Central Bohemian Region regulation No. 6/2011, effective 13 August 2011.
