Project summary

Edit project overview to modify the project summary.

Remove/modify or replace structure to enable eel passage into the river Quaggy. Could install a pumped bypass. Maintain gauging function. This is a critical depth gauaging weir for measuring water levels in the river Quaggy. The weir is a total barrier to upstream migration of eels and elvers.
