Location description
The testing point is by the stone bridge over the larger stream in the cow field. The bank edge is quite trampled by cows to the south and east of the bridge and the stream is quite wide here. To the north of the bridge it is narrower. The stream comes from springs on the Hogs Back and travels past fields with horses in and Backhurst/Strawberry Farm (soils, rocks, woodchip etc are stored and sold from here). The testing location is on a footpath and from the bridge so is accessible all year, even when the water is very high, the bridge is usually above the water. The water was flowing steadily on this occassion
