Project summary

Edit project overview to modify the project summary.


To improve habitat, fish passage, spawning and recruitment opportunities, native fish stocks and implement Water Framework Directive improvements to achieve Good Ecological Status within the catchment. Also, to decrease any risk of the property flooding, improve the ecology, repair the damage from historic dredging and land use of the grounds and create sympathetic use of the pasture land.
