Stream identification is rarely as simple as looking for the blue lines on a map. Practices to identify and assess streams vary throughout the United States. A lot can change between different State and Federal agency jurisdictions. In order to do these types of assessments, it is necessary to have knowledge of specific methods for determination of jurisdiction and flow regime.
Flow regimes can include perennial, intermittent and ephemeral flow. Depending on the location, season and recent weather, these regimes can be difficult to differentiate and the streams themselves may be hard to recognize. For example, this stream in Harlan Co., KY only carries flow in response to rainfall. Differing agencies on the State and Federal levels may treat an aquatic resource such as this in different ways.
Another factor is policy change. Legal jurisdiction over aquatic features can vary based on the current policies.
BSC is dedicated to being up to date with the current policies of State and Federal agencies in order to make accurate and efficient determinations. The staff has practiced a variety of different assessments to determine the flow regimes and functionality of aquatic resources throughout multiple states. BSC works hard to ensure that various permitting processes are accomplished successfully.
Many methods are utilized in the process of restoring a stream. The complete reconstruction of a stream can bring the work of builders, engineers, GIS professionals and biologists together to create a natural stream design.
Installation of in-stream structures is very important to create wildlife habitat and prevent erosion while maintaining aesthetics. In-stream structures can include: deflectors, cross-vanes, weirs, step pools and log jams. These structures can be used to direct stream flow, dissipate flow energy, and create pools and other habitats for aquatic species.
Several elements of stream restoration can be seen in this image: The boulders concentrate flow down the center of the channel to reduce bank erosion. Cross-vanes reduce velocity and add diversity to the water flow. Meanwhile, large local woody debris was placed throughout the reach to provide amphibian habitat and food to macroinvertebrates in the form of detritus as they decompose.
BSC has been involved in all aspects of stream restoration including the design and monitoring of in-stream structures for reconstructed streams.
Riparian zones include the plant communities along stream and river banks. Riparian zone health directly affects stream health by preventing erosion and promoting habitat biodiversity. Riparian zone plantings are integral, and often required, for stream mitigation, restoration, and enhancement. Plant species of all strata can be used to help create a healthy riparian zone. Species selection is based on ecosystem, wildlife benefit, cost effectiveness, and availability.
BSC has helped to plan, implement, coordinate and monitor many riparian zone plantings in order to re-establish healthy stream ecosystems in impacted areas. A healthy riparian zone promotes stream health through canopy cover, nutrient cycling, invasive species prevention and much more.
According to the Tennessee Department of Environment and Conservation website:
Persons who wish to make an alteration to a stream, river, lake or wetland must first obtain a water quality permit. Physical alterations to properties of waters of the state require an Aquatic Resource Alteration Permit (ARAP) or a §401 Water Quality Certification (§401 certification). Examples of stream alterations that require a permit from the Tennessee Division of Water Resources (division) include:
Dredging, excavation, channel widening, or straightening
Bank sloping; stabilization
Water diversions or withdrawals
Dams, weirs, dikes, levees or other similar structures
Flooding, excavating, draining and/or filling a wetland
Road and utility crossings
A federal permit may also be required from the U. S. Army Corps of
Engineers (Corps) for projects that include the discharge of dredged or
fill material into waters of the U.S. including wetlands. This permit is
called a §404 permit. When a §404 is required from the Corps, a §401
certification must first be obtained from the division. A §401
certification affirms that the discharge would not violate Tennessee’s
water quality standards. The application process for a §401
certification is the same as the ARAP process.
General Permits are developed and maintained by the division to
provide a streamlined, expedited means of authorizing projects that
singularly or cumulatively propose minor impacts to water resources.
Implementation of some types of conservation practices on agricultural land requires coverage under TDEC’s Construction General Stormwater Permit (CGP) and/or ARAPs. In an effort to streamline this permitting process for agencies invloved, a fact sheet was cooreratively developed to help farmers, landowners and other program participants to determine when a permit is needed or not.
Biological Systems Consultants, Inc. can provide support for the ARAP process.
According to the Kentucky Division of Water all discharges to waters of the Commonwealth require a permit through the Kentucky Pollutant Discharge Elimination System (KPDES). Such permits include effluent limitations that are developed from technology-based and water quality-based criteria. Our team of technicians can provide General and Individual Permitting and compliance services to help you navigate your project needs in a cost efficient manner.
As required by Kentucky Revised Statute 151.250, stream construction permits are required for any development occurring in, along, or across a stream. Typical projects include, but are not limited to, dam construction or maintenance, stream crossing projects (excluding KYTC), residential or commercial development, fill, stream bank stabilization, channel realignment, or impoundments. Contact us today or request a quote for your project.
National Pollutant Discharge Elimination System (NPDES) Permits are required for various projects to monitor water quality leaving a site and protect the Nation’s water resources. NPDES Permitting and Compliance is provided by our team of technical review staff and data managers. Contact us today for General or Individual NPDES permit needs for your project.

We recently completed another hydrologic determinations (HD) in Campbell County, in the State of Tennessee for the Tennessee Department of Environment and Conservation (TDEC) . These are required by Tennessee law and are conducted by our trained field staff. These determinations use a combination of primary and secondary field indicators for the assessment. The secondary indicators include assess geomorphology, hydrology, and biology related characteristics within the watercourse to identify if it is a wet weather conveyance.
We are now preparing the Aquatic Resource Alteration Permit (ARAP) for the streams identified within the site boundary and also preparing the Nationwide Permit (NWP) Application for the U.S. Army Corps of Engineers Nashville District.
We recently completed multiple hydrologic determinations in the State of Tennessee. These are required by Tennessee law and are conducted by our trained field staff. These determinations use a combination of primary and secondary field indicators for the assessment. The secondary indicators include assess geomorphology, hydrology, and biology related characteristics within the watercourse to identify if it is a wet weather conveyance.
Jurisdictional Determination projects were conducted at these Kentucky sites in the last couple months. One project was determined to not require a permit while the other was found to contain one jurisdictional intermittent stream channel.
Jurisdictional Determinations are conducted by BSC personnel in support of the requirements of Section 404 of the Clean Water Act (CWA) to identify “waters of the U.S.” as identified by the United States Army Corps of Engineers (USACE). Field surveys for the determination were conducted in accordance with the 1987 USACE Wetlands Delineation Manual (USACE, 1987) and the Final Regional Supplement for the Piedmont and Eastern Mountains Region (USACE, 2012). BSC investigators also evaluate the potential for federal jurisdiction under Section 404 of the CWA over aquatic features in the study area based on USACE revised guidance published December 2, 2008. In addition we conduct determinations in accordance with the new “waters rule” that is now in effect in 26 states.
Kentucky contains seven Level III ecoregions. These ecoregions were defined by similarities in geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The proposed project area is located within the Central Appalachians ecoregion (69) which drains 23,698 square miles. Specifically, the project is within the Level IV ecoregion 69e (Cumberland Mountain Thrust Block) which encompasses 1,083 square miles. The topography in this area is characterized as highly dissected, hilly and mountainous plateau with steep ridges, very narrow ridge tops, narrow valleys, and deep coves. 69e contains elevations ranging from approximately 980’- 4,139’ in Kentucky and contains streams with high gradients, waterfalls, many riffles, few pools, and cobble or boulder substrates (Woods et al., 2002).

Using drone technology we can provide ecological assessments using low-elevation high-resolution imagery of the ecosystem within a project area or site. Restoring and maintaining the natural environment continues to be an important issue. BSC specializes in helping clients solve the challenges of growing their businesses while addressing environmental concerns.
We conduct ecological assessments including biological, aquatic, fish, bird, plant, tree, wetland, stream habitat, and other natural resource assessments. BSC provides expertise in both water resources and aquatic systems management, which requires the understanding of input and output relationships between water systems and their its influence on natural processes. We develop client specific solutions that protect sensitive resources and infrastructure including roads, wetland habitat, rivers, streams, recreational facilities, and infrastructure.
Our client was looking to open a new operation, and hired BSC to perform a preliminary evaluation on an area encompassing 2,000 acres. Our study identified the potential of the proposed mines impacts to archaeological resources, streams and wetlands, prepared a stream restoration plan for the SMCRA permit, a jurisdictional determination or the Corps of Engineers (section 404), and a Section 401 (Water Quality Certification) for the State of Kentucky. The Corps permit was able to be avoided by revising the footprint of the permit while still achieving an economically beneficial project.
