Extremes in flow are important processes for structuring communities and ecosystem functioning in streams. Low flow events are of particular concern because it is during low flow that human water use, such as diversions, ground-water abstraction, and water use for irrigation, are in direct conflict with the maintenance of a minimum flow for ecological function. We explored the ecological impacts of low flow conditions by experimentally reducing stream flow in northeast Connecticut streams. In the summer of 2006 we altered flow over a 100meter reach in four streams for three months using water diversion stations. We had two unaltered streams as references. We monitored habitat availability, resource availability, and resource quality biweekly; aquatic insects monthly; and fish yearly for sites upstream and downstream of the water diversion stations, normal and lowered flow respectively. Despite average flow being lowered by 40-70%, and decreases in the coefficient of variation of flow, we did not see large shifts in habitat or resource availability and quality. We did, however, see a decrease in the size of fish in lower flow environments. The impacts on aquatic insect communities are currently being investigated.
