The June 2011 version of the Peninsula lake map is ready. You can download a PDF or get the SVG and the map styles from github
This version includes more buildings, docks and rocks traced into OpenStreetMap from Bing imagery along with a few bay names and some cleaner text. My next step is to try and collect depth data in some areas the that the Hydrological service skipped. I’ve already been out in a kayak with a weighted container and rope trying to develop techniques.
I have written about the newer 2012 version at https://scanningpages.wordpress.com/2012/05/06/penlake-map-may-2012/ where I talk about making the map into an web map of Peninsula Lake at http://www.mapexplorer.org/penlakemap
