Night Time Survey Work - not so much..

Todd and I dropped in to visit Morton's Wharf tonight with the intention of getting some measurements for his Divemaster Mapping Project. It turned out that working at night is not so easy. Our basic error was trying to run a tape along the bottom, rather than the top, of the various wall lines. The fact that several sections of the walls have collapsed, and that there are many logs and timbers lying adjacent to the bottom of the wall, makes running the line out difficult. We'll have another go before long, using the top of the wall to capture the relevant figures.

Otherwise, our dive was pretty good. Surface temperatures above freezing, despite light rain, were quite easy to work with. The water temperature though has dropped quite a lot over the last week. It registered 41℉ (5℃) on our computers ( drop of about 5℉ since this time last week).

There were the usual Bass and Gobies around, and Todd played with a couple of Mudpuppies. He also managed to spot a Pike lurking in the usual NW corner. I missed it.
