The data on water quality provided through the MECP “Lake Partner” program and through monitoring by the NBMCA were invaluable to preparing this report. I have addressed the comments provided by yourself and the NBMCA on our draft report in the appropriate sections and revised Figure 1 to better illustrate the basin and subwatershed distinctions. I thank you for the opportunity to work with you on this project and look forward to future collaboration. Sincerely, per: Hutchinson Environmental Sciences Ltd.
