Abstract: Twenty-four macrobenthic taxa, including 12 chironomid species, were collected from the 10 to 14 m depths in eutrophic Oneida Lake. Of the three lakes, Oneida Lake had the highest benthic production, 12.1 to 17.7 dry g.m-2.yr-1. The dominant species were the chironomids, ProcladiusPr. freemani and Chironomus plumosus-gp.

Seventy-seven macrobenthic taxa, including 41 chironomid species, were collected from 0.6 to 3.5 m depths in Deer Lake. Benthic production at four different sites ranged from 1.3 to 5.7 dry g.m-2.yr-1. Despite a relatively low density, Hexagenia limbata dominated production at all sites. Chironomids (primarily Procladius) and Chaoborus spp. were also among the dominant species in Deer Lake. Deer Lake's chironomid community and production level indicated that it was in the range between moderate oligotrophy and mesotrophy.

Twenty macrobenthic taxa, including 14 chironomid species, were collected from 10 and 19-20 m depths in South Lake. The benthic production in South Lake, which has been acidified, was 2.5 dry g.m-2.yr-1 at the 10 m depth, where Chironomus anthracinus-gp. was the dominant species. Production was 9.5 dry g.m-2.yr-1 at the 19-20 m depths, where Phaenopsectra Phaenopsectra, Chironomus salinarius-gp. and Chironomus anthracinus-gp. were the dominant species. South Lake's benthic community was similar to those from other acidified lakes.

Depth affected the voltinism of some chironomids in Deer Lake. Pagastiella ostansa, Cladotanytarsus and Tanytarsus were all bivoltine at 0.6 m depths, but were univoltine at 2.5-3.5 m depths.
