An outer margin of a lining sheet is secured to a land border of a pond by a device comprising an elongate member and a plurality of fasteners, such as metal or polymeric stakes. The elongate member defines a wall and a flange projecting from the wall, meeting the wall at a junction dividing the wall into an upper portion and a lower portion, and being divided into a series of tabs enabling the wall to flex, each tab having a preformed hole. Each fastener has a pointed shank, which is driven through the preformed hole of a respective one of the tabs of the flange, through the outer margin of the lining sheet, into the land border of the pond, whereby to secure the outer margin of the lining sheet to the land border of the pond so that the upper portion of the wall projects upwardly and defines a landscaping or hardscaping border and so that the lower portion of the wall projects downwardly into the pond to limit uplifting of the lining sheet.
