Information sign 18 - The Stream, Nobles Green Ditch
The stream that runs along the northern boundary of the park is known as Nobles Green Ditch. It is a tributary of the River Roach and originates to the west of Rochford and runs through mostly agricultural land, passing the Rayleigh water treatment works. There is a small weir close to Pooh Sticks bridge where at permitted times of the year water can be diverted, via "Dave's Dyke", to feed the lake at the west end. From the east end of the lake an overflow takes water back into the stream. There is little wildlife in the stream, though small fish have been seen and the occasional duck. Very rarely a kingfisher has been spotted as the stream flows past Blatches Farm to the point where it leaves the park under the main road. At times of heavy rain the river has been known to flood, overflowing its banks and encroaching on to the paths, adjacent meadows and farm land. More information about the stream can be found HERE.
