This lagoon no longer exists. The California Tahoe Conservancy has separated the lagoon from the adjacent marina and is restoring the wetlands that once existed before construction of the Tahoe Keys in the 1950s and 60s as part of the Upper Truckee Marsh Restoration Project. 

I would like to correct the base layer in Open Street Maps but I do not have the skills to edit away the lagoon myself. I can provide aerial images to anyone who is able to edit the base layers to ensure they depict the new landscape. 

Similarly, the trail shown on this base layer has been reconstructed to go around the lagoon. 

You can find further details on the Upper Truckee Marsh restoration project at https://tahoe.ca.gov/upper-truckee-marsh/.
