Factors Leading to Flashy Hydrology
• Channelization and snag removal
• Draining of wetlands and levee building
• Soil type and impervious surfaces
• Frequency, timing, and magnitude of precipitation events and climate change
Certain tributaries extensively channelized
Half of historic wetlands have been filled
Diverse soil types; 9% urban land use

Concepts in Stream Ecology
• Stream Order and River Continuum
• Flood Pulse in Large River/Floodplain Systems
• Channel Sinuosity and Morphology
• Stream Hydrology and “Flashiness”

Fish Diversity
• 108 fish spp. in Grand River watershed
• ~100 in Ottawa County
• One native species extirpated in watershed
• Diverse habitats and connectivity are critical

Mussels in the Grand
• 32 of 45 MI species found in Grand River
• 8 are imperiled
• Historic pearl button industry ended in 1944
• 1995 poaching case

Dams in the Grand River Watershed
• 228 registered dams
• Many no longer serve their original purpose
• Six dams with fish ladders allow passage to Lansing
• Removal has pros & cons
Hubbardston Dam on Fish Creek
Sixth Street Dam in Grand Rapids

Other Invertebrates
• Diverse dragonflies and damselflies in lower Grand
• 2009 DEQ survey found “poor” macroinvertebrates at all three Ottawa Co. Grand River sites
• Mostly chironomids and very few sensitive species
“Bloodworms” are a larval chironomids that tolerate low O2.
Many caddisfly species do not tolerate poor water quality.

Legacy of Dredging
• 1881 River and Harbor Act authorized dredging to Grand Rapids
• 1886 completion of 60’ wide 4 ½’ deep channel
• 1887 report concluded in-channel deep water connection from Grand Rapids to Lk. MI
• 1930 River and Harbor Act abandoned Grand River above Bass River
• Adjacent canal using river water proposed but never attempted…

“Historical pollution as well as the current discharges from the remaining combined sewer overflows has left the Grand River with a
reputation of being polluted. Although this was an accurate description of the past, the river has recovered and currently supports a diverse
aquatic community.
The natural resources in the Grand River catchment are substantial and provide millions of dollars of recreation-based revenue to the
residents of the watershed”
