Two Watermills and an Open Sluice near Singraven (c. 1650) is an oil on canvas painting by the Dutch landscape painter Jacob van Ruisdael.

Between the mills are three water-wheels, two on the left and one on the right, with an open sluice-gate in the centre, through which the stream rushes down.

A flight of steps goes up the right bank to a path up a hill, on the top of which, in the right distance, are a village church and a wind-mill amid trees.

"[1] This scene is very similar to other paintings Ruisdael made in this period of watermills and these often served as inspiration for later painters of landscape.

This location has been determined to be Singraven, part of Dinkelland near Ootmarsum, subject of more paintings by Ruisdael.
