South East Rivers Trust have been knocking out weirs along the Hogsmill to enable fish to pass from the Thames to the source of the Hogsmill at Ewell. The results are impressive and this improvement is at Elmbridge Meadows on the west side of the A3.
We went to look in vain for frogspawn in the seasonal pond on the Meadows. Maybe a little too early, although there are records nearer the town centre (Penrhyn Road) from 20.2.15 and at Manor Park 28.2.15.
Although with a little egret on regular patrol, the frogs will have to be quick to get to the pond.
