No mortality was observed, but several species responded by differentially drifting from the oil-impacted areas during the following days. In the arctic stream, <em>Trichotanypus posticalis</em> (Diptera) showed a significant increase in drift for the first few days. There was also an overall increase in drift of total organisms post spill. <em>Phaenospsectra</em> sp. 1, the numerical dominant, decreased its nocturnal drifting compared with the upstream control station in the 5 days post spill. In the subarctic stream, <em>Skwala</em> sp. 1 (Plecoptera), <em>Prosimulium</em> sp. 1 (Simulidae) and <em>Pseudo-diamesa</em> sp. 1 showed significant increase in drift post spill. Among the species of benthic invertebrates sampled with a Hess sampler (WILDCO, Saginaw, Mich.), only the density of <em>Nemoura</em> sp. 1 declined significantly post spill.

In addition, the large-sized, over-wintering instars present had a low surface area per unit volume, which reduced absorption of volatiles, reducing the probability of any massive mortality.
