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 insertion of an LP shunt is usually indicated when the amount of CSF fluid in the subarachnoid space is more than usually desired. The other end of the shunt tubing or catheter is routed into the peritoneal cavity, an area in the abdomen and drains the excess CSF fluid here.
