Flooding
Flooding has always been a major problem
with watersheds. Flooding causes erosion and sometimes damages
buildings and other structures that are in the rivers way. The
further downstream, the more potential for damage during flash
flooding.

Flood debris hangs on a tree along
the Tohickon Creek in Bedminster, PA. |

A high water mark dated 8-19-55 on
River Road north of Point Pleasant shows how remarkably high water can
get during a flood. |
Dams have been built to help solve the problem
of flooding. The dam holds the water back and allows only a certain
amount of water through at a time. Sometimes dams can be found
all along the watershed rivers. They can reduce flooding problems,
but can also cause other environmental concerns such as blocking
migrating fish species, hurting water quality, and not allowing
for seasonal changes. Two local dams are located in our region
one at Lake Galena and the other at Lake Nockamixon. There are
alternatives to building new dams which may also reduce flooding
damage. These include removal of structures in flood plains and
better storm runoff controls.

Lake Galena is a Bucks County Park
lcoated just South of our school district. |
|
Lake Nockamixson State Park was created
with a large earthen dam. Show here is the cement spillway. |
The East Branch of the Perkiomen Creek runs
through the length of our school district. During times of significant
rainfall it is difficult to cross this waterway anywhere in our
school district. The creek shown below flows into the East Branch
of the Perkiomen Creek which has already overflowed its banks
behind the covered bridge in Lenape Park. September 1999 - Hurricane
Floyd.

Flooding at a runoff creek leading
to the East branch of the Perkiomen Creek in Perkasie, PA. This normally
small waterway flows into the East Branch of the Perkiomen Creek . |

After the flood waters have gone down,
the same location is viewed when the runoff creek is relatively high.
Contrast the two photos and what is covered by water. |

During the same flood caused by Hurricane
Floyd in September 1999 the playground at Frank R. Kulp Memorial Playground
in Perkasie, PA is covered by water the East Branch of the Perkiomen Creek. |

A ball field in Sellersville, Pa is
also part of the flood plane for the East Branch of the Perkiomen Creek. |
