Slackwater darter [Etheostoma boschungi]

The slackwater darter ranges from 1.6 to 3 inches in length. It is characterized by a blue-black bar under the eyes, and by three prominent dark dorsal saddles. This fish feeds on insects and small crustaceans and lives no more than three years. It is found in small to moderate, slow-flowing upland streams no more than 40 feet wide and less than 7 feet deep, or in wider streams with overhanging banks without riffles or rapids. This species has distinct breeding habits that rely on spring rains in seepage areas such as open fields, pastures or woods where they spawn in water approximately 3 inches deep.

Historically, populations of the slackwater darter were probabally more widely distributed throughout smaller streams of the Tennessee River basin. Current populations are found in limited numbers in five tributaries in the south bend of the Tennessee River: Buffalo River and Shoal Creek (Lawrence County), Tennessee; and Flint River (Madison County), Swan Creek (Limestone County), and Cypress Creek (Lauderdale County), Alabama.

The slackwater darter's habitat has been significantly reduced due to falling water tables throughout the region. Heavy groundwater use for agricultural and human consumption has dried up many seepage areas and closed off numerous spawning areas. Current threats to the remaining populations are herbicides, pesticides, industrial wastes, and sewage which enters the groundwater stystem and degrades water quality.

Boulder darter [Etheostoma]

The boulder darter, also known as the Elk River darter, has a maximum length of 3 inches and is olive to gray in color. Because few specimens of this fish have ever been collected, not much is known about its history or biology. It is found in deep, fast moving water over boulder and slab rock bottoms.

The boulder dartar has been found within a 43 mile range of the Elk River in Giles County, Tennessee and Limestone County, Alabama, in addition to 2 mile stretches of Indian and Richland creeks in Giles county, Tennessee.

The major factors affecting the habitat of the boulder darter is stream and river alterations, such as change in water temperatures and impoundment, that are direct results of dam construction in this region. Other factors, such as increased siltation, agricultural, industrial and other toxic chemical runoffs, could further threaten existing species and its habitat.
