Lower Saluda River
The Congaree Riverkeeper’s geographical area includes the Saluda River from below the Lake Murray dam to its confluence with the Broad River to form the Congaree.
Geographical Area
The Lower Saluda River flows out of the Lake Murray dam and merges downstream with the Broad River to form the Congaree River in the City of Columbia. The Lower Saluda Basin contains the Town of Lexington, Gilbert, Summit and Irmo, and portions of the Cities of Columbia and West Columbia. Rawls Creek, Lorick Branch, and Kinley Creek drain into the Saluda River near the City of Irmo.
Juniper Creek and Long Creek join to form Twelvemile Creek near the Town of Gilbert. Twelvemile Creek flows through the Town of Lexington, and accepts the drainage of Fourteenmile Creek before discharging into the Lower Saluda. The Lower Saluda River follows a generally straight southeastern course with mostly forested riverbanks, except in the vicinity of occasional transmission line crossings or developments.
The river can be described as mostly low-gradient pools and glides with occasional riffles in the upper reach, and a somewhat higher gradient lower reach with pools, riffles, and rapids over bedrock and boulder substrate, particularly where the river cuts through the fall line near Columbia.
The river becomes braided with several side channels and islands at the confluence with the Broad River. Major transportation routes in the Basin include S.C. 6, which runs from the Lake Murray dam south through the Town of Lexington; U.S. 1 and U.S. 378, which run west from the City of West Columbia and intersects with Highway 6 in Lexington; and I-26, running southeast from the Upstate to the Midlands and on to Charleston; and I-20, running east from Aiken County through the Midlands and further on to the Pee Dee Region.
The Lower Saluda Basin is mostly located in Lexington County with a small portion in Richland County.
Land Use
Land cover in the watershed includes:
- 48.6% forested land,
- 25.6% urban land,
- 20.2% agricultural land,
- 2.8% forested wetland (swamp),
- 1.8% water,
- 0.9% barren land, and
- 0.1% nonforested wetland (marsh).
The Towns of Lexington, Irmo, and Gilbert have grown rapidly in the past and are expected to continue this trend.
Parks, Protected Areas and Recreational Access
State Scenic River
A 10-mile segment of the Saluda River beginning one mile below Lake Murray Dam to its confluence with the Broad River was designated a State Scenic River by the Legislature on May 31, 1991. The Lower Saluda Scenic River is recognized as an outstanding recreational resource. The tailrace waters from Lake Murray reservoir provide a cold water fishery and varying water levels for recreational boating.
Trout and striped bass fishing as well as whitewater (class II to V rapids) and flatwater paddling are very popular on this piedmont river. These factors, combined with the surrounding topography and rock outcrops similar to mountain streams and the heavily wooded landscape, make the Lower Saluda River corridor an outstanding natural resource within the urban environment of metropolitan Columbia.
The original Lower Saluda River Corridor Plan was developed by a local Lower Saluda Scenic River Advisory Committee in 1990. This plan presented over 70 recommendations for the long-term management of the river. The corridor plan was updated in April 2000. The plan is implemented through voluntary efforts by riparian landowners.
Saluda Shoals Park
Saluda Shoals Park is a 350-acre regional park located along the north side of the upper section of the Lower Saluda River. In addition to educational and conference facilities, it offers hiking, biking and horseback riding, a river observation deck, river bank access, and boat ramps for small boats, canoes, and kayaks.
Riverbanks Zoological Park and Gardens
The Riverbanks Zoo is a 170-acre zoo, botanical gardens and aquarium located along the Saluda River. It is South Carolina’s largest gated tourist attraction, averaging 1 million visitors a year. The Zoo is home to over 3,000 animals and over 4,000 plant species are located within its botanical gardens.
Public Boat Landings
Access by boat can be made at Hope Ferry Landing on the Lexington side of the river and at Saluda Shoals Park on the Irmo side. Further downstream is the boat ramp at Gardendale on the north side of the river before the I-20 bridge. Access is also possible for canoes and kayaks near Candi Lane just upstream of the Zoo, but there is no public parking.
Wildlife
Fish and Mussels
The Lower Saluda River supports an important sport fishery for both coldwater and warmwater species. The coldwater fishery is possible because of the cooler than normal water released from Lake Murray, and is maintained by annual trout stockings by DNR of approximately 30,000 trout, with about 75% brown trout and 25% rainbow trout.
Typical length at stocking is from 7 to 10 inches, but rainbow trout of 4 to 8 pounds have been caught, indicating some carryover of fish from year to year in spite of low levels of dissolved oxygen in the fall months. Warmwater species occurring in the lower Saluda River include chain pickerel, redbreast sunfish, redear sunfish, bluegill, largemouth bass, carp, channel catfish, spotted sucker, yellow perch, sandbar shiner, and gizzard shad.
Striped bass are present in the Lower Saluda during their spawning season. Striped bass from the Santee Cooper lakes migrate upstream to the Congaree, Wateree, Lower Broad, and Lower Saluda rivers to spawn in the spring, and also use the cooler Lower Saluda River as a thermal refuge during the summer months. American Eel also exist in the Lower Saluda.
In 2006, SCE&G sponsored a comprehensive mussel survey of Lake Murray and its tributaries, the Lower Saluda River, the Broad River, and the Congaree River. Sixteen freshwater mussel species were collected and identified within the areas surveyed, including: common elliptio, variable spike, Carolina lance, northern lance, Atlantic spike, Roanoke slabshell, Carolina slabshell, Florida pondhorn, paper pondshell, eastern floater, creeper, eastern creekshell, yellow lampmussel, rayed pink fatmucket, and lilliput species (Toxolasma parvus).
Distribution of mussel species varies according to habitat, with species tolerant of lacustrine habitat occurring within Lake Murray, and lotic species more common in riverine habitat.
Birds
Within the Riverbanks Zoo area, bird habitat can be heavily fragmented and degraded, but the extensive trail system affords the opportunity to see interesting species. The rocky shoals, the steep hardwood bluffs of Riverbanks Zoo, and the area upstream of the diversion weir provide habitats that attract interesting and unique bird species. Spring and fall warbler migrations are inconsistent from year to year, but can be impressive.
Some of these migrants include: Canada Goose, Red-breasted Merganser, Hooded Merganser, Horned Grebe, Mallard, Double-crested Cormorant, Anhinga, Great Egret, Snowy Egret, Little Blue Heron, Osprey, Bald Eagle, American Kestrel, Killdeer, Spotted Sandpiper, Caspian Tern, Forster’s Tern, Belted Kingfisher, Eastern Kingbird, Barn Swallow, Cliff Swallow, Northern Rough-winged Swallow, Brown Creeper, House Wren, Philadelphia Vireo, Magnolia Warbler, Bay-breasted Warbler, Yellow Warbler, Chestnut-sided Warbler, Cape May Warbler, Black-throated Blue Warbler, Prairie Warbler, Blackpoll Warbler, American Redstart, Prothonotary Warbler, Northern Waterthrush, Common Yellowthroat, Hooded Warbler, Yellow-breasted Chat, Field Sparrow, Swamp Sparrow, Rose-breasted Grosbeak, and Orchard Oriole.
Saluda Shoals Park’s extensive riverside and powerline easement trail system affords the opportunity to see many of the same bird species as seen in Columbia’s downtown parks, along with many field species. The park is often one of the best places near Columbia to see spring and fall migrants, so a near-comprehensive list of migrating warblers has been included here. Some piedmont species are highlighted as well.
Sightings include: Hooded Merganser, Green Heron, Mississippi Kite, Red-shouldered Hawk, Broad-winged Hawk, American Kestrel, Spotted Sandpiper, Belted Kingfisher, Olive-sided Flycatcher, Acadian Flycatcher, Eastern Phoebe, Northern Rough-winged Swallow, Barn Swallow, House Wren, Blue-gray Gnatcatcher, Eastern Bluebird, Wood Thrush, Gray Catbird, Cedar Waxwing, Blue-winged Warbler, Golden-winged Warbler, Tennessee Warbler, Orange-crowned Warbler, Yellow Warbler, Chestnut-sided Warbler, Magnolia Warbler, Cape May Warbler, Black-throated Blue Warbler, Black-throated Green Warbler, Blackburnian Warbler, Prairie Warbler, Palm Warbler, Bay-breasted Warbler, Blackpoll Warbler, Cerulean Warbler, Black-and-white Warbler, American Redstart, Prothonotary Warbler, Worm-eating Warbler, Swainson’s Warbler, Ovenbird, Northern Waterthrush, Louisiana Waterthrush, Kentucky Warbler, Common Yellowthroat, Hooded Warbler, Canada Warbler, Yellow-breasted Chat, Scarlet Tanager, Swamp Sparrow, Rose-breasted Grosbeak, Blue Grosbeak, Indigo Bunting, and Painted Bunting.
Threatened or Endangered Species
Six species of federal concern may be found within the Lake Murray/Lower Saluda River area: Carolina Slabshell, Roanoke Slabshell, Carolina Lance, Savannah lilliput, Yellow Lampmussel, and Rayed-Pink Fatmucket.
The endangered shortnose sturgeon is believed to exist in the Lower Saluda River for short time periods during spawning season. The endangered Carolina Heelsplitter may also exist in the Lower Saluda River watershed.
As for other wildlife, the American Bald Eagle, once endangered but recovering, is also known to exist within the watershed.
Surface Water Hydrology
Streamflow in the Lower Saluda River has been monitored continuously since 1925 at a gage located about .5 mile above Riverbanks Zoo. Another USGS gage located below the Saluda Project dam has been in operation since 1988. Major tributary streams that feed the Lower Saluda River include Twelvemile Creek and Fourteenmile Creek on the south (Lexington) side of the river and Rawls Creek, Kinley Creek, and Sloop Creek on the north (Irmo) side of the river. The tributary streams have not been monitored for streamflow.
Average flow in the Saluda River near Columbia is 2,762 cfs and has ranged from a low of 12 cfs in 1930 to a peak flow of 67,000 cfs in 1929. Flows in the Saluda River have been influenced by regulated releases from the Saluda Hydroelectric Project since its completion in 1930. Historically, minimum flow releases from the Saluda Project have been 180 cfs; however, recommendations by the resource agencies to FERC for the new operating license increase the minimum flows to at least 700 cfs for most of the year and higher in April and May. This should result in less flow variability and higher low flows in the future.

Surface Water Quality
The Lower Saluda River is unique in its water quality classification for a Midlands river due to cold water releases from Lake Murray, resulting in cooler than normal water temperatures. It is classified as "Put, Grow and Take" Trout Waters (TPGT). By state standards, Class TPGT waters are freshwaters suitable for supporting growth of stocked trout populations and a balanced indigenous aquatic community of fauna and flora.
They are also suitable for primary and secondary contact recreation and as a source for drinking water supply after conventional treatment in accordance with the requirements of the Department; suitable for fishing and the survival and propagation of a balanced indigenous aquatic community of fauna and flora; and suitable also for industrial and agricultural uses. All other streams are classified as "freshwaters."
The Trout Water classification supports a popular trout fishery created by deep coldwater discharges from Lake Murray. The Department of Natural Resources stocks about 30,000 Rainbow and Brown trout annually to maintain the trout population, which is unable to reproduce. However, these same deepwater (hypolimnetic) discharges also result in low dissolved oxygen (DO) levels in the Saluda River. Since 1999, SCE&G has reduced the problem by making modifications to project operations and equipment to improve aeration.
Even though the daily average DO has increased from 2.7 mg/L to 7.2 mg/L and instantaneous levels have improved, DO levels still do not meet state water quality standards all the time. Consequently, DHEC has included in its 401 Water Quality Certification for the relicensing of the project the requirement that SCE&G must make additional modifications to meet state DO standards in the river "under all operating levels and conditions" within an agreed upon time frame.
The table below lists all waters in the Lower Saluda River Basin identified by DHEC as impaired, that is, not meeting recreational and aquatic life water quality criteria. High fecal coliform levels are the greatest water quality problem causing impaired recreational use in the basin. Recreational use is impaired at seven locations including Kinley Creek, Lorick Branch, Rawls Creek, the Saluda River, and Twelvemile Creek. Poor macroinvertebrate assemblages account for impaired aquatic life uses at five sites. High turbidity and low DO impair aquatic life uses at two sites and one site, respectively.
Many sites have had approved TMDL's since 2004 but still do not sufficiently meet water quality criteria. Fish flesh analysis from the Saluda River below Lake Murray Dam indicates high levels of mercury (Hg). Consequently, DHEC has issued a public health advisory for consuming certain fish species in the Saluda River from the Dam to its confluence with the Broad River. They advise that people limit consumption of largemouth bass, chain pickerel, and bowfin (mudfish) to one meal per week.
