Too much water on the marsh.
Sunrise: 05.03 Sunset: 09.09
There is too much water on the marsh! How can there be too much water on a marsh, some of you must be thinking. Well, it’s true! We have too much water on the island, and too much water on the mainland. It’s not just a matter of my feet getting wet either; the high water levels are negatively affecting some of the rare marsh flora, such as the indicator plant marsh cinquefoil.
Some rare wetland plants will tolerate deep water in winter, but struggle to survive during the growing season without effective water level management: they might become ‘swamped’ by water doc, reeds or yellow flag irises, for instance.
The solution is simple: we increase water flow from the marsh into the river by progressively removing sluice boards until the waters reach acceptable levels.
The south marsh sluice is easily accessible at the south pool. There isn’t a sluice on the island, so we will have to do a bit of ditching and install one.
