10Primary Protection Efforts
Protect riparian buffer and stream habitat
Reduce agricultural impacts Stream Quality
Monitoring Project Reduce impacts of
urbanization Dam Removal
11Benefits of Dam Removal
Safety Hazard drowning hydraulics
12Benefits 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
-
13Benefits of Dam Removal Ecological
Excessive sedimentation - substrate embeddedness
14Macroinvertebrates
Live in interstitial spaces critical level in
food chain
Unionid Mollusks
Sediment on gill surface causes decreased food
filtering efficiency and asphyxiation
15Simple 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
16Dam 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

21Dam 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
22Macroinvertebrates
Utilized Hester-Dendy samplers per OEPA protocol
Monitoring 7 sites, some samplers lost in high
water first year
