This last Thursday Shaun Gardner and Ben Griner dove on a new target resting upright in 170' ffw North of 520 in Lake Washington. This dive was to survey the vessel and determine it approximate age and type. Our drop was excellent today with the ball landing in the mud just to the south of the vessel. Shaun tied the drop line in and we began to swim around the vessel. This ship is just over 40' in length with a beam of approx 12'. The vessel was obviously scuttled with most objects of value having been removed. The engines, screw, and other equipment have been removed.
This side scan image gives a good representation of the vessel we dove today. What originally appeared as equipment on the front deck was really loose railing and bow structure.
Shaun Gardner crawls into the cabin area. This is a back-up drysuit for Shaun as his first one experienced a failed zipper just prior to the dive. This wreck is now labeled "zippy" until we can determine its real naming.
The construction is all wood with limited electrical wiring added after construction. There is a name physically engraved on the stern but we were unable to make it out on this dive. Remnants of the Washington State registration number are present on the bow. Unfortunately these identifiers are of little value as the State of Washington DOT has refused to assist with the identification of these shipwrecks.
A total of 25 minutes was spent on this wreck followed by a two bottle decompression. Decompression was uneventful with Scott Christopher acting as captain and picking us up after the dive.
Puget Sound Divers is actively evaluating several potential targets in Lake Washington. This weekend our team obtain side scan imagery of what appears to be an intact vessel. Below are the side scan images of the wreck.
This image is looking down on the vessel. Note the open hatches on the stern. I am guessing that this was cut to access the engines prior to scuttling the vessel.
This image was taken from the side of the vessel. The shadowing shows the main cabin area and pilot house. The forward railing is visible with some type of boom or equipment item on the forward deck. Looking closely at the stern mud line you will see the side scan passed under the vessel suggesting is largely rests above the bottom.
Survey dives will be conduced on the vessel over the next week. Based on the side scan imagery obtain the vessel is estimated to be 55-62 feet in length and standing just shy of 25' above the mud layer. Resting in 167' of fresh water this vessel is resting upright and appear to have the majority of its keel above the bottom.
