The northerly canal around the Geerpolder (Ommedijkse watering), seen from the bridge on the westernmost corner in NE direction. At the left is the Blankaartpolder, at the right the Geerpolder which is visibly below the water level in the canal. (actually about 4 meters/12 feet)
The building with the red rooftiles is one of the pumping stations for the Geerpolder.
