[Tweeters] Question: Channel Drive-Shorebirds and tides. What is the highest tide level that shorebirds feed at Channel drive?

[Dan Reiff via Tweeters]

Hello Tweeters,
September is such a sweet month in Western Washington. I look forward to it every year. Many good options for observing birds.
I had planned on filming sandpipers and yellowlegs at channel Drive this evening between 4 and 8 PM.
However, I read that the high tide was at 4:19 PM and stayed pretty high until several hours later. So assumed 7-8 feet would cover the mud flats and the birds would not be present.
I would appreciate Responses to my question regarding channel Drive and tides:
What is the highest tide level that shorebirds feed (water shallow enough for the birds to reach the mud)at Channel Drive?

Thank you,
Dan
