H. ajax was found at one site above and two sites below the Pueblo dam in the Arkansas river. Quote from page 62: "Although no stoneflies were collected downstream
of Pueblo Reservoir, the hydropsychids Cheumatopsyche pettiti and Hydropsyche occidentalis and the hydroptilids Hydroptila ajax and Ochrotrichia stylata were dominant at AR19 and AR20. [downstream of the reservoir]"
