Lake Darling was once among the state's most polluted. Silt had shrunk the 1952 reservoir from 305 to 267 acres and high bacteria levels often closed it to swimming. Today, thanks to 80% participation of landowners and farmers, terraces and farm ponds have cut sediment reaching the lake from about 16,000 tons a year to less than 7,000.

ReplyDeleteThe agents of Soil erosion are the same as the agents of all types of erosion: water, wind, ice, or gravity. Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away.
ReplyDeleteActivities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.
