The Broads restoration programme aims to recreate clear water with healthy aquatic plant growth which provides a habitat for wildlife.
It includes the reduction of nutrients in the water which encourage algae to grow, making the lakes and rivers cloudy.
In addition, water fleas like to graze on algae controlling its growth, but large populations of small fish keep the numbers of water fleas down by eating them. In order to resolve this, the fish need to be removed. This technique of stimulating the natural biological processes in a lake is called biomanipulation.
Restoration requires a combination of complex techniques to re-establish clear water and submerged plant species in the longer term.
You can read in more detail about how we deliver the programme in the Lake Restoration Strategy which sets out the future direction for the restoration of the Broads. The accompanying Lake Restoration Strategy Action Plan outlines priority actions and details future projects to be delivered over the course of the five year programme.
