Location: Savannah River main channel
[Remember that here you need to describe the type of aquatic system within the context of the riverscape that occur within that system. The more detailed you are, the more information you incorporate from our discussions, our visits, and the reading assignments, the easier it will be for me to clearly see you learned a lot and applied information you learned ***note that you can incorporate in images to help illustrate your points – on the next page I provide an example of how I would do a field assessment]
• What kind of aquatic habitats are available to fishes here? For each of those aquatic habitats, what do you think the corresponding water quality attributes are (water clarity, level of oxygen, etc.)
• What does the surrounding terrestrial habitats look like and how could impact the aquatic habitats?
• What additional aquatic animals occur at this field site? How might they interact with local fishes?
• What kinds of terrestrial animals occur at this field site (types of mammals, birds, herps, etc)? How might they interact with local fishes?
• Describe what you think the benthic substrate is composed of.

Location: Savannah River main channel
On 21 Jan 2021, the class visited sites associated with the main channel of Savannah River. We walked along the bank at the Savannah River Bluff Lock and Dam.
The main river channel of the Savannah contains an assortment of habitats spanning the length of its bendy reach and from side to side.
The main channel of a river is one part of the larger riverscape system that also includes habitats reaching across the entire floodplain. Adjacent to the channel, but directly connected includes tributaries that empty into the main channel, floodplain swamp, wetland systems that receive the spill over waters from the main channel, former river channel components, some created naturally from the long-term shifting of the river (oxbow lakes, sloughs, side channels) and some created when the river channel was modified by humans.
One major driving characteristic that is important about the main river channel is that the water is constantly flowing from upstream to downstream, this is the classic example of a lotic system. The speed of the water flow varies within the main channel depending on the amount of water released from upriver dams and also from rain events. Across the channel flow also varies depending on the part of the river; in the zones where the river flows straight, the velocity of the water is relatively consistent, but where the river bends, flow is more rapid on the outside part of the bend versus the inside.
Substrate types of main river channel:
The river contains a sandy bottom base and other types of substrate occur along the way increasing in size such as gravel, cobble, on up to boulder like structures. The bottom of the river also contains sunken debris such as trees that fell in the river and branches and mulch from the surrounding terrestrial areas that have washed into the main channel. All of this structure contributes to the availability and diversity of habitat that exists and supports the various organisms living in the channel. The more complexity of habitat, the more types of fish species that a system can support.Water clarity:
The clarity of the water in the main channel varies depending on the inputs. When water is released from dams upstream then this can cause the water clarity to decrease because of the churning up of sediment. Similarly, when it rains a lot, the sediment from the terrestrial environments being transferred into the river and make it look more muddy. The stuff in the water that makes it less clear is a combination of organic and inorganic material – both provide various types of nutrients to the system and can contribute to increases in the overall productivity.Flow:
The main river channel is a lentic system meaning that water is constantly flowing there. Flow varies spatially and temporally and this can contribute to the diversity of fish species the river supports because different fishes have evolved and adapted to thrive in different regions of the region of river characterized by a continuum of current speed.Oxygen:
The main river channel is characterized by high oxygen levels and this is related to the constant moving of the water. Regions of the river where flow is limited have lower oxygen levels.
Savannah River Bluff Lock and Dam
The Lock and Dam was a great example of how humans have impacted the main channel of the Savannah River, changing aspects of the habitat for those organisms that reside in the river. We also saw evidence of urbanization.
Human Modifications:
The middle Savannah River occurs in association with several populous counties of Georgia and South Carolina; Richmond County, Columbia County, and Aiken County all contribute to an increase over the last 100 years in impervious surfaces (roofs, roads, paved driveways) which corresponds with a decrease in the natural vegetation of the surround upland regions directly impacting the river system. When it rains, water cannot infiltrate into the ground like it naturally does in forested environments and instead ends up washing into the streams and creeks that form the tributaries of the river. This runoff from the rain and impervious surfaces increases the chances of flash flooding and carries with it contaminants and trash that end up in the river.Dams create impediments for fish that need to migrate upriver for foraging and breeding, this is another way that humans modify river systems and may negatively impact the fishes in the river.
Channelization – the straightening out of portions of the channel along a river also causes major disturbances. This alters river flow, causes the input of sediments that could contain low levels of oxygen. Often associated with channelization is the constructions of levees, or walls along the sides of the river which negatively impacts the natural overflow process of the river when water moves into floodpain swamps. Many fish rely on the swampy areas for foraging and breeding so this can disrupt their life cycle.
Important habitats that are of note and may contain interesting fishes:
The banks of the river where the water has eroded portions of the underside of the banks around tree roots are structurally complex and provide great habitat for a lot of different fish species.Areas with rocks along the banks also provide a lot of complexity and will support a lot of fishes.
Areas with vegetation, similarly will provide some complexity and may support additional fishes.
Predictions on which species we may encounter when sampling this area:
Table 5 in the chapter on Savannah River and Swamps listed several potential species we may encounter from the river channel.
Bowfin – we actually saw a dead bowfin on the bank at this site, probably thrown there by one of the anglers.
Atlantic and shortnose sturgeon – these species occurs in the main channel and migrates upriver to spawn
Longnose gar
American eel
Spotted sucker
Snail bullhead
Yellow bullhead
Channel catfish – nonnative species
Flathead catfish – nonnative species
Mosquitofish
Brook silverside
Redbreast sunfish
Hogchoker
Warmouth
Bluegill
Largemouth bassAdditional aquatic and terrestrial organisms:
Lots of bird species occur in association with river channel habitat. We saw blue herons and white egrets which can feed on fish in shallow areas along the shore. Osprey also occur along the river and eat fishes.Deer, geese, ducks, many amphibians and reptiles also occur in or around the main river channel.
Within the water there are a diversity of insects and other small invertebrates that fishes consume. There are also crayfish and freshwater mussels.
