The markers in the Kent Narrows North Channel are back to normal, the way they are used to be. No more temporary floating markers.Stay as much as possible in the middle of the channel. Shallow areas are after the 3&4 markers and at the 5&6 markers.I don't know what the MLW is because I draw 6' and will only attempt to pass through the channel at High Tide +- 2 hours.
Unless the NW wind is blowing strong the water depth should be 6' or more. The last 2 weeks we had the SSW blowing strong and pushing the water up north. This should hold through the weekend, unless a low pressure front comes through. Be aware there is also a hump with very shallow depth just north of the drawbridge entrance, right under the high route 50/301 bridge. I got stuck there and it took me a few minutes to get off. The bridge operator was nice enough to hold the bridge open for me.The bridge operator requests to be called on channel 13 just 3 minutes before the opening at the hour and 1/2 hour.
