On a subsequent telephone conversation I had with him though, they were not interested in spearheading the project, and since I, Shalom M. Mandaville, live in Dartmouth, it was not convenient for me to drive back and forth as a total volunteer. In addition, my priorities have always been in continuing my research in Applied Limnology.
As it is, I spent a horrific amount of time driving back and forth all the way from Dartmouth almost on a monthly (and sometimes on a biweekly) basis during the period, 1991-92, carrying out field sampling as a total volunteer assisted mostly by an extremely dedicated/concerned local resident, Mr. Walter Pilon, and on a couple of occasions, by a resident of the Sheldrake Lake subdivision, Mr. Terry Conrad.
Because of the reasons explained in the preceding paragraph, I abandoned the project until a handful of members of another local group, the Woodens River Watershed Environmental Organisation, (WRWEO), expressed an interest in carrying out the project.
Several further discussions took place via meetings and emails during 1999-2001, and on our suggestion, WRWEO obtained the services of a reputed lake aeration specialist, Mr. Kenneth Ashley, of the B.C. Ministry of Fisheries. WRWEO has been instrumental in obtaining a major Federal funding (EcoAction) among other sources, and hopefully all of our efforts will lead to success.
Relevant excerpts from the report by Mr. Kenneth Ashley have been inserted towards the end.
>Hello, I would like to get access to vertical oxygen and temperature profile data for Sheldrake Lake so I can provide Tim McGee and Frank Hope with advice in designing a hypolimnetic aeration system for Sheldrake Lake.
Your assistance would be greatly appreciated.

Mandaville, thank-you very much for your detailed comments re: the background on Sheldrake lake. All I need is the field data from 1991-92 for oxygen and temperature. Regarding the oxygen-temperature data, I once again tried to download the data from the web site that you indicated http://www.chebucto.ns.ca/Science/SWCS/DATA/data-s.xls, and I am unable to do so (semi-web illiterate I guess).
Is it possible to simply forward me the Excel files of the oxygen-temp data for the few years that Sheldrake was sampled on at least a monthly basis in the summer and winter so I can make some estimate of the hypolimnetic oxygen demand. It would be greatly appreciated.
I would like to compete my report for Woodens River as quickly as possible so that they get the correct picture on what hypolimnetic aeration can and cannot do, and do not waste any of their money on "pie in the sky" ideas. I agree with your comments, and my report will reflect that, including the issue of non-point source nutrient loading and sustainability.
