In May 2013 we found ourselves rushing back from Lake Erie to address the St Lawrence Institute's 20th Annual Symposium on the Great Lakes / St. Lawrence River Ecosystem, on the subject of "St Lawrence tributaries in Ontario as refuges for Unionid Mussels." Several of these tributaries are crossed by the Enbridge/Transcanada pipelines, and consideration of their refuges must be part of planning for any changes to the pipelines.
