The River Aire flowing through Saltaire's Roberts Park is just... only just... contained within its banks at the moment. This area is almost like a little beach in summer. You can see grasses at the edge of the channel where the river normally flows. There were lots of ducks (mallard) in this area of shallows. Perhaps the water is a little warmer here? Or maybe it suits their dabbling habit to be in a shallow area, out of the rushing currents.
