Kronenburger See

Kronenburger See is a detention basin in Dahlem and Hallschlag that collects and stores water from the Kyll river system. The basin features a main dam and pre-dam, with walking paths around the water's edge providing access to its shores.

Construction of the detention basin began in 1968 and was completed in 1986 to manage flood waters from the Kyll system. The finished project became part of the region's water management infrastructure.

The shoreline has become a gathering place where local communities spend leisure time together. Paths wind around the water, offering spaces where people walk, rest on grassy banks, and enjoy recreational pursuits.

The site offers various activities for visitors, from walking trails to paddling and rowing boats available for rent. The southern shore remains car-free, making it ideal for leisurely walks without vehicle traffic.

The water is home to several fish species including brook trout, rainbow trout, pike, and zander that attract anglers throughout the year. This fish population makes the basin a sought-after fishing destination in the area.
