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.
What is a shunt? A shunt is a tube, akin to plumbing, that diverts cerebrospinal fluid (CSF) from the brain to an alternate compartment in the body (in most cases the abdominal or peritoneal cavity). A shunt is implanted to treat hydrocephalus or excess fluid in the brain (with resultant enlargement of the ventricles).
