Summary
The Nature Conservation Agency of the Czech Republic (AOPK ČR) restored the Černý potok (Black Brook) in the Černá louka Nature Reserve (Ore Mountains, near Adolfov). Early trials began in 2001–2003; the main works in 2009–2010 (OP Environment/ERDF) went beyond in-channel fixes: shallow, meandering channels were newly excavated and reconnected to remnants of the historical course or led across alluvial meadows to reduce depth/volume, slow runoff and re-wet the peat meadows. Designed by Terén Design and built by EPS-Servis, the project reshaped ~2.5 km within the reserve and delivered c. 1,820 m of new channels, ~0.963 ha of ponds/wetland and an ~8 ha meander belt.
Post-restoration monitoring by UJEP found only very small lateral movement (≤10 cm), no significant incision, and that after 1980s straightening had shortened length by ~52% the restored reach in 2011 was ~43% longer than the straightened channel. AOPK notes continued monitoring and documented fish passage, incl. brown trout spawning. Media coverage during the 2019 drought reported the area stayed wet and ponds held water. In 2022, ČSOP with private partners extended restoration to a small tributary just outside the reserve.
