Watersheds and estuaries Rachel L. Kennison

What is a Watershed??? A watershed can be found almost anywhere. It is defined as the flow of water from a high to low place, over or under land. Whenever you see a creek, stream, river, delta, lake or ocean you see a part of the watershed.

What’s happening to the Watershed? Local watersheds are in danger from many threats such as agricultural runoff, acid rain, development and more. Processes like Acidic Mine Drainage only further the problem, while utilizing products such as Bio-diesil will slow it down. The kinds of dangers created result in problems that can only be seen down stream. This usually means that actions taken by local politicians reflect a view that nothing is wrong because they can not see anything on their doorstep.

Agricultural Runoff Agricultural runoff is one of the leading causes of bad water quality that affects our lakes, rivers, and other waterways.

Why Is Agricultural Runoff A Problem? Runoff can pick up various substances These pollutants flow directly into sewer systems, lakes, streams, and rivers. During storm water overflow, anything that enters a storm sewer system is discharged untreated into the water bodies we use for swimming, fishing, and providing drinking water. It can take centuries for some water bodies to recover.
