Scenic Rivers Program

2
Scenic Rivers Program
Program Goal To work cooperatively with local
governments, businesses, landowners, non-profit
organizations and other state and federal
agencies to facilitate the protection of Ohios
remaining high quality stream systems Scenic
River Law, ORC Section 1517.16 Local
community support
3
Scenic River Designation
  • Resolutions of support
  • Study team and designation study
  • Recommendation to the director
  • Intent to designate
  • Public comment period hearings
  • Journal entry

4
Ohios Scenic Rivers
  • First program in the nation, started in 1968
  • 21 designated streams totaling 722 miles
  • Scenic River Watersheds drain about 13,611
    square miles

Primary Protection Efforts
Protect riparian buffer and stream habitat
Reduce agricultural impacts Stream Quality
Monitoring Project Reduce impacts of
urbanization Dam Removal
11

Benefits of Dam Removal
Safety Hazard drowning hydraulics
12
Benefits of Dam Removal Ecological
  • Negatively impact biological community
  • Riverine to lacustrine loss of riffle, pool
    run complex
  • Lower species diversity, tolerant spp.
    predominant
  • Lower water quality, D.O.
  • Impede natural movement of bed load

13
Benefits of Dam Removal Ecological

Excessive sedimentation - substrate embeddedness
14
Macroinvertebrates
Live in interstitial spaces critical level in
food chain
Unionid Mollusks
Sediment on gill surface causes decreased food
filtering efficiency and asphyxiation
15
Simple Lithophils
- need a hard, clean, rocky substrate to lay eggs
on - provide no parental care
Shorthead Redhorse Moxostoma macrolepidotum
Benthic Insectivores
- need a hard, clean, rocky substrate feed on
macroinvertebrates
Hog Sucker Hypentelium nigricans

Dam Removal Sandusky State Scenic River
  • St. Johns Dam
  • Constructed 1935 by Ohio-American Water Company
  • Backup water supply for the city of Tiffin
  • Inspection in 1999 by ONDR, Division of Water
    determined the dam was unsafe
  • 150 feet long, 7 feet high
  • Impounded 8.5 miles of Sandusky River

St. Johns Dam ResearchProject Partners
  • Macroinvertebrates Heidelberg, Dr. Ken
    Krieger
  • ODNR, Division of Natural Areas and Preserves
  • Bivalve Unionids OSU, Dr. Tom Watters
  • Fish ODNR, Division of Wildlife, Natural Areas
    and Preserves
  • Geologic mapping of stream ODNR, Division of
    Geological Survey, Lake Erie Group
  • Qualitative Habitat Evaluation Index (QHEI) -
    Ohio Department of Transportation
  • Additional independent research OSU, Dr. Tim
    Granata
  • Sites monitored before after removal 5 yr.
    study

21
Dam Removal St. Johns Dam Research
  • Monitoring sites above and below dam
  • Monitoring at Ohio Environmental Protection
    Agency reference sites
  • Detailed mapping was completed by the ODNR
    Division of Geological Survey 9/22/03 to 11/4/03
  • Post dam removal mapping was performed in
    7/26-27/04, 10/25/04, and 10/27-28/04

22
Macroinvertebrates
Utilized Hester-Dendy samplers per OEPA protocol
Monitoring 7 sites, some samplers lost in high
water first year
