MANAGE WATERWAY AREAS IN 56 OF OHIO’S 88
COUNTIES


ACCORDING TO THE ODNR, DIVISION OF
WATERCRAFT’S
2002 OHIO SURVEY OF RECREATIONAL
BOATER OPINION
, OF THE PUBLIC ACCESS
WATERWAYS LISTED, OHIO STATE PARKS MANAGE
ALMOST 72% OF THE ACRES OF THE WATERWAYS
IDENTIFIED


ACCORDING TO THE OEPA’S,
305(b) (STATE OF THE
LAKES) REPORT
(2000), OF THE PUBLICALLY OWNED
LAKES IN OHIO, OHIO STATE PARKS MANAGE OVER
52% OF THOSE LAKE ACRES


ANNUALLY, THE OHIO STATE PARKS REPORTS ALMOST
8,000,000 BOATER OCCASIONS







SEDIMENTATION


ITS SOURCES
AND IMPACT ON BOATING


LAKES ARE PART OF LARGER ECOSYSEMS CALLED
WATERSHEDS


SOIL AND DEBRIS ARE CARRIED TO WATERWAYS BY
WATER RUNNING OFF THE WATERSHED


SOIL EROSION FROM FARM FIELDS, CONSTRUCTION
SITES, STREAM BANKS, TIMBERED AND OTHER AREAS
FINDS IT WAY INTO STREAMS, RIVERS AND LAKES


IN OHIO, OVER 5,OOO,000 CUBIC YARDS OF SOIL
ERODES FROM NON
-
FEDERAL CROP, CRP AND PASTURE
LANDS ANNUALLY


SEDIMENTATION OCCURS WHEN THE SOIL SINKS TO
THE BOTTOM OF THE WATERWAY


OVER TIME, SEDIMENT AND DEBRIS BUILD UP,
REDUCING OPPORTUNITIES FOR SAFE RECREATIONAL
BOATING




SHALLOW WATERS LIMIT
RECREATIONAL BOATING

WATERSHED APPROACH


DREDGING, BY ITSELF, IS A “BAND AID” APPROACH TO MANAGING
SEDIMENTATION


A WHOLISTIC WATERSHED APPROACH WORKS TOWARD A “CURE”



WATERWAYS REFLECT THE LAND USE IN THE WATERSHED


EXCESSIVE SEDIMENTATION CAN BE A SYMPTOM OF POOR
WATERSHED MANAGEMENT


INCORPORATION OF BMP’s HELP PROTECT OHIO’S WATERWAYS


EXAMPLES OF BMP’s INCLUDE… CONSERVATION TILLAGE,
STREAMSIDE FILTER STRIPS, STORMWATER RUNOFF BASINS,
COVER FOR DISTURBED SOILS, PROTECTION OF WETLANDS AND
OTHERS


OHIO STATE PARKS ENJOYS PARTNERSHIPS WITH OTHER
AGENGIES AND CITIZEN GROUPS THAT HELP TO IMPROVE
WATERSHED CONDITIONS TO THE BENEFIT OF RECREATIONAL
BOATERS




ROLE OF DREDGING IN

OHIO STATE PARKS


DREDGING IS THE PROCESS OF UNDERWATER
EXCAVATION TO DEEPEN A WATERWAY BY REMOVING
ACCUMULATED SEDIMENT


IN OHIO STATE PARKS, THE PURPOSE OF DREDGING IS
TO “FOSTER VESSEL SAFETY” AND OTHER ANCILLARY
BENEFITS MAY RESULT


EXCESSIVE SEDIMENTATION CAUSES WATERWAYS TO
BECOME SHALLOW AND A HAZARD TO OHIO STATE
PARKS’ RECREATIONAL BOATERS


REMOVING ACCUMULATED SEDIMENT IS A PRACTICAL
WAY TO INCREASE WATER DEPTH, AND


DREDGING IS A WIDELY RECOGNIZED AND
RECOMMENDED TECHNIQUE FOR REMOVING
SEDIMENT

PRIORITIZING PROJECTS


MANY WATERWAYS IN OHIO SUFFER FROM
THE EFFECTS OF SEDIMENTATION AND
DREDGING IS IN DEMAND


MORE PROJECTS THAN TIME OR EQUIPMENT


PRIORITIZATION IS BASED UPON A NUMBER
OF FACTORS INCLUDING… BOATER USE,
FUNDING AVAILBILITY, QUANTITY OF
ACCUMULATED SEDIMENT AND IMPACT TO
BOATING, AVAILABILITY OF A RELOCATION
AREA, EQUIPMENT ACCESS, LOGISTICS AND
EMERGENCY SITUATIONS

PERMITTING


DREDGE AND FILL ACTIVITIES ARE
REGUALTED BY THE U.S. ARMY CORPS
OF ENGINEERS AND OHIO EPA THROUGH
THE CLEAN WATER ACT OF 1972


BEFORE ANY DREDGE OR FILL ACTIVITY
IS INITIATED THE APPROPRIATE ARMY
CORPS OFFICE NEEDS TO BE
CONTACTED AND APPROVAL SECURED

FUNDING


FUNDING FOR THE OHIO STATE PARKS’ WATERWAY
IMPROVEMENT PROGRAM COMES FROM THE DIVISION
OF WATERCRAFT’S WATERWAYS SAFETY FUND


A BOATER GENERATED FUND


NO GRF MONIES
SUPPORT THE FUND


CHIEF OF THE DIVISION OF WATERCRAFT MUST
APPROVE EACH OHIO STATE PARK DREDGING PROJECT
PAID FOR THROUGH THE FUND


PRIVATE GROUPS AND INDIVIDUALS CAN FUND
PROJECTS


OTHER FUNDING MAY COME FROM GRANTS OR THE
OHIO STATE PARKS OPERATING OR CAPITAL
IMPROVEMENT BUDGET

DREDGING CRITERIA


THE DIVISIONS OF PARKS AND RECREATION
AND WATERCRAFT DEVELOPED A LIST OF
SEVEN “DREDGING CRITERIA” THAT PROVIDE
GUIDANCE FOR THE APPROVAL OF DREDGING
PROJECTS TO BE FUNDED THROUGH THE
WATERWAYS SAFETY FUND


THE GENERAL CONCEPT OF THE CRITERIA IS
TO PROVIDE FUNDING FOR PROJECTS THAT
SERVE THE GREATEST NUMBER OF BOATERS
USING OHIO STATE PARK WATERWAYS, YET
TAKING INTO CONSIDERATION HISTORIC
PRACTICES

CHIEF ON BOARD


BUCKEYE DREDGE

DREDGING EQUIPMENT


TWO TYPES OF DREDGES ARE USED TO
REMOVE ACCUMULATED SEDIMENT…


HYDRAULIC SUCTION DREDGE AND


MECHANICAL DREDGE


SUPPORT EQUIPMENT INCLUDES
BULLDOZERS, LARGE TRUCKS AND
TRAILERS, FRONT
-
END LOADERS,
TRACTORS, WORKBOATS AND BARGES

BULLDOZER

HYDRAULIC SUCTION DREDGE


IMAGINE AN EGG BEATER ATTACHED TO A
VACUUM SWEEPER


BEATER, OR CUTTERHEAD, AGITATES THE
SEDIMENT


PUMP CREATES A VACUUM THAT PULLS THE
WATER/SEDIMENT MIXTURE THROUGH AN
INTAKE HOSE


THE PUMP THEN PUSHES THE SLURRY
THROUGH A PIPELINE TO A RELOCATION AREA

HYDRAULIC SUCTION DREDGE

MECHANICAL DREDGE


BETTER KNOWN AS A CRANE, TRACK HOE OR
EXCAVATOR


USES AN ARM AND BUCKET TO EXCAVATE
ACCUMULATED SEDIMENT


CAN DIRECT DEPOSIT TO RELOCATION AREA
OR TO TRUCK OR VESSEL FOR TRANSPORT TO
RELOCATION AREA


CAN ALSO BE USED TO CONSTRUCT
RELOCATION AREAS OR SHORELINE PROJECTS

MECHANICAL DREDGE

RELOCATION OF

DREDGE MATERIAL


DREDGE MATERIAL RELOCATION AREA (DMRA)


CRITICAL TO DREDGING PROCESS


OHIO STATE PARKS USES TWO TYPES OF
DMRA’s… UPLAND AND IN
-
WATER


UPLAND IS THE PREFERENCE


DMRA’s ARE DESIGNED TO RETAIN SEDIMENT,
ALLOWING CLEAR WATER TO RETURN TO THE
WATERWAY

DMRA

BENEFICIAL USE OF

DREDGE MATERIAL


GENEREALLY CLEAN, FERTILE SOIL


MATERIAL HAS BEEN USED FOR
LANDSCAPING, ROADWAY AND RUNWAY
CONSTRUCTION, FARMLAND
ENHANCEMENT, BEACH NOURISHMENT
AND RECREATION AREA IMPROVEMENTS


DREDGE MATERIAL FOR WETLAND
CREATION OR ENHANCEMENT

BENEFICIAL USE… WETLANDS


A PRODUCTIVE
PURPOSE


BENEFICIAL TO
ENVIRONMENT


HABITAT AND WATER
QUALITY


SERVES TO
MITIGATE NEGATIVE
IMPACTS


DRAWBACKS TO DREDGING


COSTLY


TIME CONSUMING/INCONVENIENT


BENTHIC ZONE DISTURBANCE


TURBIDITY


RESUSPENSION OF CONTAMINENTS


NUTRIENTS


HEAVY METALS


GOOD PLANNING LIMITS THE DRAWBACKS





SUMMING IT UP


OHIO STATE PARK WATERWAYS PROVIDE
GREAT OPPORTUNITIES FOR ALL KINDS OF
BOATERS


WATERWAYS REFLECT THE LAND USES IN THE
WATERSHED


SOME USES MAY CAUSE SEDIMENTATION


SEDIMENTATION REDUCES SAFE BOATING
AREAS


IMPLEMENTATION OF BMP’s AND WELL
PLANNED DREDGING PROJECTS CAN RESTORE
BOATING OPPORTUNITIES


OHIO STATE PARKS

VISION STATEMENT






“…TO ENSURE A
LASTING LEGACY
WHICH WILL FEED
THE HOPES AND
ASPIRATIONS FOR ALL
GENERATIONS.”



and CHIEF SEATTLE SAID…

“WE DID NOT
INHERIT THE
EARTH FROM
OUR ANCESTORS,
BUT ARE
BORROWING IT
FROM OUR
CHILDREN.”
