 Though the weir at Teddington Weir marks the managed river's usual tidal limit, after prolonged rainfall causing very high fluvial flow, specifically at high tide, a higher limit of slack water (stand of the tide) causes eddies to arise as far upstream as the top of this reach, the next lock.The large, bow-shaped Teddington Weir is against the opposite bank.A series of two footbridges at differing heights make up a structure which crosses the locks, the middle island that has the lock keeper's cabin and the weir pool, Teddington Lock Footbridge.
