Cambarus miltus has been assessed as Least Concern. This species has a relatively wide distribution, with an extent of occurrence of 17,000 km2. Furthermore, it is not thought to face any major threat at present. It is more common than previously thought.
|Range Description:||This species is known from a limited portion of the Escambia River drainage in extreme southern Alabama and western Florida (Taylor et al. 1996). Schuster and Taylor (2008) recently documented several dozen new occurrences in Alabama and Florida. This species is found in one site in Baldwin County, Alabama (Fitzpatrick 1978) 6 records near the type locality in Baldwin County, Alabama, 2 records from Covington County and further records from Corn Branch and Negro Creek in Baldwin County (Fitzpatrick 1991, Mirarchi et al. 2004, Schuster and Taylor 2004, Schuster et al. 2008). In April 2007, according to the Florida Natural Heritage Program (FL NHP) a small female was collected in McDavid Creek, Escambia County, Florida (D. Jackson, FL NHP, pers. comm. 2007 cited in NatureServe 2009). Schuster and Taylor (2008) reported this species from 31 sites, in 10 basins (including Mobile Bay, Perdido River, Perdido Bay, Blackwater River, Pascagoula Bay, Mississippi Sound, Fish River, Choctawhatchee Bay, and Choctawhatchee Bay) in Covington and Mobile counties, Alabama, and Escambia, Holmes, and Washington counties, Florida.
The extent of occurrence (EOO) of this species has been estimated to exceed 17,000 km2.

|Population:||The population in Daphne's D'Olive Creek, south Baldwin County, Alabama, is healthy and is estimated to equal hundreds, if not thousands, of individuals (Raines 2007). This species has recently been shown to be much more common than previously thought (Schuster and Taylor 2008).|
|Habitat and Ecology:||This species is a primary burrower (Fitzpatrick 1978). It lives within 50 m of flowing water but is intolerant of saline intrusion into groundwater.|
|Major Threat(s):||It is unknown whether this species is impacted upon by any major threat processes. However, it is unlikely to be undergoing any significant threat (R. Thoma, T. Jones and J. Cordeiro pers. comm. 2009).|
This species has been given a Global Heritage Status Rank of G3 by NatureServe (Taylor et al. 2007, NatureServe 2009) and Threatened by the American Fisheries Society (Taylor et al. 2007). However, recent surveys have indicated it is much more common than previously expected (R. Thoma, T. Jones and J. Cordeiro pers. comm. 2009).
Further research is required to determine abundance and major threats.
