But after what time is it an ecosystem that has to be protected?
We have here the “Lüneburger Heide” with a lot of protected species and take great care to keep it a heathen. It is an artificial landscape and was woodland before all the trees were chopped off to cook salt in Lüneburg. It was kept clear by sheep. Shepherding on an open plain is now unprofitable and if we would stop now to pay the shepherds a complete ecosystem would vanish and be overgrown by bushes and trees. That would hurt biodiversity and tourism. But it would be the natural environment for northern Germany.
Is it a reservoir? If it’s a man-made reservoir you are not expecting or desiring it to become a natural ecosystem. Your primary goals are to keep the water there and keep it clean.

But a functional ecosystem keeps the water clean. You can have either a complete system with complex food chains or chlorine.
