Broad Colney Lakes
A peaceful refuge for both wildlife and people, where great crested grebes breed.
The three lakes at this reserve are quite different from one another: one is fed by the River Colne, one is relatively still and deep and the smallest has partially developed into marshy woodland. A variety of land and water birds can be found here. Great crested grebes can be seen on the lake, along with tufted ducks, whilst in the alder trees flocks of siskins feed, along with mixed flocks of finches and tits. Otters travelling up and down the River Colne pass through the reserve.
