I have been keeping an eye on some videos from http://www.abay.com/, Over 30 years boating in the area I have observed High and Low water conditions, but can't recall anything like this year. Other than the flooding problems, I would imagine there are some shoals that would normally be above water that are submerged without warning buoys. Any other "hidden hazards?" I will be there for three weeks starting July 8th. Is there a projected date for return to normal?

Watch for submerged fixed docks and wharfs when approaching marinas, parks, etc ... they are starting to show up again but are just inch or two above water, some are still submerged while sticking out 30-50, even 70 feet into the lake/river.

Another thing to plan for is gas ... many gas docks were flooded, not sure when they will start operating normally. Good news ... water is coming down on the most eastern part of the lake and river, 3-4 inches since the dam opened the gates 36 hours ago. Hopefull no new heavy rains somewhere up the Great Lakes.

Here are two sources for river and seaway info ...

USACE monthly projection of mean water level for July was scary two inches above May levels. That should not happen if they keep the dam gates open. You can subscribe to Seaway Recreational Craft Bulletins to get an updates on Seaway conditions, restrictions, etc.

BTW, just for the curious ones ... if you want to meet or avoid a ship on the Seaway, here is a map with ship locations and transit info: http://www.greatlakes-seaway.com/en/navigating/map/index.html

How much have conditions changed since June 15th? Coming up this Saturday.

Not much ... there was a rapid and noticeable difference in the two/three days after the dam opened. Since then the lakes upstream and our area had a lot of rain, including downpours once or twice every week. The water level is maybe 3-4 inches down from the highest but still 3-4 feet above the seasonal average.

Since we are still getting used to having a cruiser, we decided to postpone our trip to 1000 Islands.  I guess its probably not a bad year to skip.

Yes and no ...

Yes ... The debris is still floating but not much of it anymore. The marinas and services are still affected but adapted by now.

No ... You have deep water everywhere. Places that were iffy can be approached with more confidence. Generally more water under the keel and less chance to strike that pesky rock shelf that appeares from nowhere.

Update ...

The water level is another few inches down, and the trend is decisively down now. We are close to a foot down from the highest levels in late May and early June.
