Depending on the amount of rainfall about 3-14 springs flow out from the Kalkugrava slope. They accumulate into a small lake. The water temperature doesn't change through year and stands on 7°C. Lake's bottom consists of blue clay.
In the valley of Kalkugrava there is a watermill built of traveline by the uncle of the famous latvian sculptor T. Zalkalns. The name of the ravine comes from an old limekiln that exists no more.
