Kolks and drinking pools

This file contains kolks and drinking pools that have arisen as a result of dike breakthroughs in the past. A dike is a water-resistant construction, usually thrown up earth and whether or not covered with stones or asphalt. Designed to protect land behind it from flooding. As a result of dike breakthroughs, a number of kolks have been created in the past, some of which have been preserved in the landscape. The province of Groningen focuses on the preservation and possible restoration of landscape and culturally valuable dikes and the associated elements such as kolks, drinking caps, denominations and shot beam sheds. These mainly old sleeper dikes are characteristic of the Eemsdelta, the Oldambt and the Wadden Coast area. The old dikes can be affected by agricultural use, in particular by levelling and cracking grassland. Also the filling and closing of the bowls and drinking caps, and the breaking down of denominations and bulkhead sheds is a loss of the characteristic value. To prevent this, the Provincial Environment Regulation 2016 lays down rules for the protection of the old dikes and the related supporting elements.
