Literature Review of Freshwater Classification Frameworks
-
Identifying aquatic ecosystems requires a classification of stream and lake features into recognizable categories. Although a number of nationally recognized terrestrial community classifications exist, currently there is no national or international standard for classifying aquatic communities or ecosystems. Despite the lack of a national aquatic community classification, aquatic ecosystem classifications and frameworks have been developed at a variety of spatial scales to reflect the distribution of aquatic biological communities. This report reviews these freshwater classification frameworks, providing detailed analysis and application examples of taxonomic, environmental, and hydrologic classifications in use within the Appalachian region.

Literature Review of Freshwater Classification Frameworks
-
Identifying aquatic ecosystems requires a classification of stream and lake features into recognizable entities or categories. Although a number of nationally recognized terrestrial community classifications exist, the most accepted being the National Vegetation Classification System (Grossman et al. 1998), currently there is no national or international standard for classifying aquatic communities or ecosystems. Despite the lack of a national aquatic community classification, aquatic ecosystem classifications and frameworks have been developed at a variety of spatial scales. Their goal is often to reflect the distribution of aqutic biological communities. These assemblages recur across the landscape under similar habitat conditions and ecological processes (Higgins et al. 2005). The methods used to develop aquatic ecosystem classifications vary widely, as do the biotic and abiotic variables considered in the classifications. The classifications generally fall into two broad categories: 1) taxonomic or bio-ecosystem classifications and 2) environmental or geo-physical ecosystem classifications (Rowe and Barnes 1994); however some classifications combine aspects of both.

Mapping our Rivers in High Definition
-
A project video produced by Tennessee Wildlife Resources Agency (TWRA) for Trutta Consulting LLC High Definition Stream Survey (HDSS) of the Caney Fork River below Center Hill Dam. The project was supported by the Cumberland Chapter of Trout Unlimited, Tennessee Department of Environment and Conservation and TWRA. We also worked with TWRA fisheries sampling crew to video and GPS their trout surveys that were completed at the same time as the HDSS project. This allows us to see the conditions that the fish were captured and determine what areas of the river are best for trout at different flow conditions.

N.C. Wildlife Resources Commission’s Whirling Disease Response Plan
-
On July 27, 2015, whirling disease was confirmed in rainbow trout collected from Watauga River in Watauga County– the first occurrence of the disease in North Carolina. Whirling disease affects fish in the trout and salmon family with rainbow and brook trout, two species found in North Carolina waters, being the most susceptible. The disease, caused by the microscopic parasite Myxobolus cerebralis, damages cartilage and skeletal tissue in trout, causing them to swim in a whirling motion.

Partnering to Connect Citico Creek
-
Dam removal projects are best done in partnership and one of the best examples is the Upper Citico Creek dam removal project in Tennessee’s Cherokee National Forest highlighted in our short film Connecting Citico Creek. American Rivers teamed up with two federal agencies, the U.S. Fish and Wildlife and the U.S. Forest Service, to achieve the common goal of restoring aquatic habitat. Each partner brought their expertise and resources to the table to produce an efficient, high quality, low cost victory in the Little Tennessee River watershed.
