Bruce, I agree with doing more fishing!
For what it's worth, I used one of those smartcast fish finders to map out the depth. There were absolutely zero fish shown anywhere on the display. As far as I know the device is in good working condition, I use it when fishing from a kayak a bit.
What other information would be useful in working out a plan? That way the next time I am there I can be sure to collect the pertinent information.
There was only a single picture taken of the fish caught this weekend, so I hope it has all the detail you need.
