Fishing in Glassmill!

Netting the fish

As part of the refurbishment project, on 21st March the water level in the pond was drastically reduced. Beforehand however a specialist contractor was on site to collect all the fish in the pond, they were recorded then released safely downstream. Altogether some 140 three-spined sticklebacks, 2 small roach and 3 eels, the largest being 79cm long, were collected.

The water flow was carefully measured. Then with the weir boards removed the water level reduced rapidly at first, exposing more of the silt deposited over many years.

The newly exposed silt now will be allowed time to dry out, before contractors are able to move in to excavate and reuse the silt to recreate a working river channel and a separate pond, that fish, eels etc can thrive in.

Glassmill refurbishment project update

As part of our ongoing project to bring this historic mill pond back to its earlier glory, we continue to work with other parties to greatly enhance its historic and ecological value. Led by Thames21 this project also involves amongst other stakeholders; Bromley council (as site owner), Environment Agency, Thames Water, and of course our Friends group.

Last Friday, Thames21 staff met up with Friends at the site, off Glassmill Lane, to carry out an important survey of the pond. They measured those features required to refine the design of the renovated pond, and for an important food risk assessment.

This flood risk assessment, and approval by the Environment Agency to dredge and reuse the silt as part of the new pond design, is critical to this project being viable. This decision is complicated by some of the silt samples previously found to contain medium levels of pollution. To read about the background to this pond and its refurbishment go HERE.
