The correct answer is: Set conditions to limit the amount of lake water people may use. Usually, this would be done by the water regulating agency by allocating water user licenses that specify how much water they are allowed to use. This ensures that these is sufficient water to meet the needs of all users, with some water users having a higher priority than others, such as a town is given a higher priority to extract water for municipal use than a farmer's use of water for irrigation. To set licenses, a scientific hydrological modelling study can be conducted to quantify the typical inflow of water into the lake. A water resources modelling study can assess how much water can be removed from the lake without compromising the lake and meeting the needs of all the water users.
