Lake Segliņi (also known as Lake Dambes, Dambezers, Lake Segliņa, or Segliņezers) is a subglacial body of water located in Renda Parish, Kuldīga Municipality. Positioned in the central part of the parish within the Mordanga lake group, it lies adjacent to the local road V1284. The lake covers an area of approximately 29 hectares, with an average depth of 0.8 meters and a maximum depth of 3.0 meters. A single island measuring 3.8 hectares is situated in the eastern section of the lake.
The eastern and western shores of the lake are relatively steep, whereas the northern and southern ends are low and flat; the bed consists of sand and mud. Several drainage ditches feed into the lake, while the Dzelzāmurupe River flows out toward the Abava River. The lake's history is tied to historical industry: in 1646–1647, a ironworks foundry and nail forge operated upstream near its outlet. The lake was drained in the 1960s during river regulation works, but its water level was restored in 1968 following road reconstruction. The historic "Segliņi" homestead is located on its eastern shore.
