The blacknose dace prefers swift streams (Traver 1929; Harlan and Speaker 1951; Scarola 1973). Greatest densities of blacknose dace adults occur when surface water velocities are between 15 and 45 em/sec (Gibbons and Gee 1972). The species is common at gradients of 11.4 and 23.3 m/km, but almost entirely absent at 67.2 m/km (Burton and Odum 1945).

Moapa dace likely inhabited 25 springs and approximately 16 km of the upper Muddy River (Ono et al. 1983). Historically the Muddy River was 30 miles long, however in 1935, with the completion of the Hoover Dam, Lake Mead flooded the lower 8 km of the river, rendering it unsuitable for Moapa dace. Recent investigations found adult Moapa dace.
