Acting on a recommendation from dam safety experts
with the Department of Environmental Protection (DEP),
the Pennsylvania Fish and Boat Commission (PFBC)
will submit a plan for notching the spillway at
Dutch Fork Lake in Washington County.
The Commission had lowered the lake when flooding
in the fall of 2004 damaged the dam’s emergency
spillway. A fish salvage operation was held in
conjunction with the draw down. The lake remained
drained until recent heavy rains in the area
temporarily refilled the impoundment last weekend.
While the rainfall that caused the lake levels to
rise dramatically was an unusual event, DEP and PFBC
engineers agree that excavating the spillway down to
bedrock will prevent any future such phenomena.
“The dam at Dutch Fork Lake is characterized as a
‘high hazard dam,’ meaning if the structure were to
fail there would be a significant risk of downstream
property damage. While there is no immediate threat
of dam failure at this time, excavating the spillway
is a precautionary measure in the interest of public
safety,” said PFBC Executive Director Dr. Douglas
Austen.
“We have experienced two extremely wet years in
Pennsylvania, resulting in emergency dam breaches
and decisions to empty some popular ponds and lakes,
including Dutch Fork,” DEP Deputy Secretary of Water
Management Cathy Curran Myers said. “DEP and the
PFBC are working closely in this case to prevent
further damage, hasten repairs and ensure the
removal of any risk to downstream residents.”
Once the work plan is approved, Commission
construction crews will move into the area to remove
the spillway. The dam breast will remain in place.
Long-term plans call for armoring the dam breast and
building a new concrete spillway. The work planned
for excavating the spillway would have been required
before any rebuild could occur. The cost estimate
for the refurbishing of the dam is in excess of $3
million and the PFBC has no money for the larger
project.
Statewide, the Commission faces a
$100+ million backlog of infrastructure needs.
Commission operations are funded from the sale of
fishing licenses and boat registrations. Currently
there is no funding source the agency can tap into
to address major capital project needs, such as
rebuilding the dam at Dutch Fork Lake. A Green
Ribbon Panel created by the General Assembly and
Governor Rendell is actively exploring legislation
to address a wide scope of environmental and natural
resource funding needs. The draining of Dutch Fork
Lake further illustrates the importance of including
funding for PFBC projects in any future funding
initiative.
Public access to the spillway area will be closed
once excavation work begins. |
