Ophiogomphus incurvatus occurs in the piedmont/foothills on either side of the Appalachians from Alabama to Maryland. It is known from 20 streams in five states and the larvae susceptible to pollution. The species is declining because of the unusual susceptibility of the larvae to flood scouring and pollution. Nearly meets criteria for B1ab(iii).
|Previously published Red List assessments:|
|Range Description:||Endemic to the United States. Occurs in the piedmont/foothills on either side of the Appalachians from Alabama to Maryland (NatureServe 2006).|
Native:United States (Alabama, Maryland, North Carolina, South Carolina, Tennessee, Virginia, West Virginia)

|Population:||Current population size is unknown.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Clear streams at low elevations in the open, with sandy or gravely riffles (Dunkle 2000).|
|Major Threat(s):||Larvae are susceptible to alterations in stream flow due to clear cutting/deforestation, agriculture, and development that produce flood scouring, siltation and pesticide use (NatureServe 2006). Chemical control of gypsy moths might be a problem (NatureServe 2006).|
|Conservation Actions:||Populations of O. I. Incurvatus are found in the Pisgah National Forest of North Carolina, Patuxent Wildlife Research Center of Maryland, and a Clemson University research area and the Savanna River Plant in South Carolina.|
