The lake is technically a pond (rybník) created by damming, making it one of the oldest in the Czech Republic.
It was historically named 'Velký rybník' (The Great Pond) before being renamed in honor of the Czech romantic poet Karel Hynek Mácha.
Karel Hynek Mácha used the lake as a primary inspiration for his famous narrative poem 'Máj' (May).
The lake is relatively shallow, with a maximum depth of approximately 12 meters near the dam.
The area is home to the specific ecosystem of the Kokořínsko sandstone labyrinth, featuring unique rock towers and caves.
The island 'Myší zámek' (Mouse Castle) in the middle of the lake is a protected nature reserve.
The lake serves as a habitat for protected waterfowl, leading to strict zoning for swimming and boat transit.
During the winter, the lake surface frequently freezes, allowing for skating, though this depends on annual climate conditions.
Lake Mácha is a large recreational pond originally commissioned by King Charles IV in 1367 for fish farming. Located in the Liberec Region, the lake covers approximately 284 hectares and serves as the primary water recreation destination in the Doksy area. The surrounding landscape features sandstone rock formations and pine forests characteristic of the Kokořínsko-Máchův kraj Protected Landscape Area. Visitors utilize several designated sandy beaches, including the Main Beach in Doksy and the beach at Staré Splavy. The lake is fed by the Břehyňský Creek and serves as an important site for water sports, including sailing, pedal boating, and windsurfing. A significant portion of the lake is surrounded by managed forest trails suitable for hiking and cycling. Recreational activity centers around the town of Doksy and the village of Staré Splavy, which provide the primary infrastructure for tourism. The water quality is generally monitored throughout the summer season for recreational safety.

Bring water shoes, as parts of the lake bottom are sandy but can contain vegetation.
Use the bicycle trails connecting Doksy and Staré Splavy for a scenic route away from the road.
Visit the less crowded northern shore trails if seeking a quieter experience than the main beach area.
Avoid the main beach entrances during peak weekend afternoons in July and August when overcrowding occurs.
Recreational services, rentals, and organized beaches are only operational during the summer season, typically from May through September.
Respect designated swimming zones and refrain from entering restricted ecological breeding areas on the islands.
