Vodná nádrž Ružiná
A fairly large recreation reservoir by Divín in the Lučenec district, surrounded by chalets and hotels, with easy entries from its many beaches. Summer visibility is only 1–2 m, and at the thermocline at 3–3.5 m it drops to about 0.5 m; the bottom is muddy with very few plants. Fish seen include carp, chub and common bream (Abramis brama). A 2019 entry said the reservoir was reportedly going to be drained that autumn.
Tiefe: 0–20 m
