Natural springs and groundwater feed the lake, keeping the water levels relatively stable year-round.
The surrounding landscape is largely flat, providing clear sightlines across the entire lake basin.
Erholungsgebiet Karlsfelder See is a 24-hectare recreational site featuring a man-made lake created from former gravel extraction pits. The lake spans approximately 10 hectares of water surface, surrounded by extensive lawn areas used for sunbathing and recreation. Dedicated zones for charcoal grilling are scattered throughout the park. The facility includes two large playgrounds and integrated sports fields for visitors. Water quality is monitored regularly throughout the summer season. A paved circuit path encircles the lake, popular for walking, running, and cycling. The park serves as a primary local recreation hub for the Karlsfeld and Dachau region.
