Many parts of Pipe Creek are so shallow that the stream gage is no longer under water. The stream gage will need to be moved further toward the center of the creek to be effective. Sandusky, Ohio.
Shallow Creek Sites

Shallow Creek Sites
Many parts of Pipe Creek are so shallow that the stream gage is no longer under water. The stream gage will need to be moved further toward the center of the creek to be effective. Sandusky, Ohio.
Shallow Creek Sites
Many parts of Pipe Creek are so shallow that you can see directly through the water to the bottom. This makes sampling difficult, since disturbing the sediment is almost inevitable. Sandusky, Ohio.
