 |Project summary=Two weirs were removed and the site allowed to drain. A temporary dam was built at the top of the site and river flow was piped around the working area. Working from the upstream end, a new channel was dug through the accumulated silt following the line of preferential flow. Nicospan was installed to provide support to the new channel sides and to ensure separation of the silt from the gravel infill, which was imported to form the new river bed. It was important to allow at least 500mm of gravel to provide the depth that chalkstream invertebrates require for their life stage. Excavated silt was distributed around the site within the boundary of old ponds. The new channel was tied into the original course of the river which flowed around the back of the island in the lower pond. A low-lying bund was installed in place of the weir to create a wetland feature. Following completion of the river restoration work, new paths were laid in the gardens and an interpretation board installed.

			In the 1970s, Meades Water Gardens, previously a public amenity area, was re-landscaped to create formal water gardens, through excavation of the beds and river. However, the ponds rapidly lost their wildlife and aesthetic value. The project planned to regenerate the Meade Water Gardens through the removal of weirs and the re-introduction of gravel beds.

			Project design
			Two weirs were removed and the site allowed to drain. A temporary dam was built at the top of the site and river flow was piped around the working area. Working from the upstream end, a new channel was dug through the accumulated silt following the line of preferential flow. Nicospan was installed to provide support to the new channel sides and to ensure separation of the silt from the gravel infill, which was imported to form the new river bed. It was important to allow at least 500mm of gravel to provide the depth that chalkstream invertebrates require for their life stage. Excavated silt was distributed around the site within the boundary of old ponds. The new channel was tied into the original course of the river which flowed around the back of the island in the lower pond. A low-lying bund was installed in place of the weir to create a wetland feature. Following completion of the river restoration work, new paths were laid in the
