| The salmon boxes at the upper weir provided fast flowing well aerated water. |
| Through the extensive studies done in the area we know that raising the weir is the only way to go. |
| Sometimes on an exceptionally high tide the water flows over the weir causing a tidal effect as far up as Kingston. |
| There is a pleasant walk of about a kilometre alongside the race as far as its headworks, where a weir on a mountain stream intercepts the water. |
| The half weir was constructed to keep a good head of water in the river between Richmond and the end of the tidal flow at Teddington weir. |
| Follow the river upstream from the weir for about two hundred yards and you will come to a clearing. |
