The watershed program offers technical assistance to watershed groups, municipalities, and individual citizens. A watershed is a geographic area of land across which water, and the sediments and dissolved materials it contains, flow on their way to a single common outlet -- a stream, lake or river.
A lumbar peritoneal (LP) shunt is a technique of cerebrospinal fluid (CSF) diversion from the lumbar thecal sac to the peritoneal cavity.
The purpose of the shunt is to reduce the amount of CSF in the brain by draining it to the abdomen or directly into a chamber of the heart. This shunting of CSF helps reduce the pressure on the brain. A shunt is a hollow plastic tube that is placed in the ventricle of the brain.
