Thank you Joel and everyone for the help on this. Here is the short summary that we have compiled so far. If the facts are wrong or if things are missing, more help would be appreciated.
Olympic Lake – originally designed by Willie Watson and Sam Whiting circa 1926
The Olympic Club’s Lake Course in Daly City, California has hosted several U.S. Amateurs and U.S. Opens. In 1918, the club took over the Lakeside Golf Club, which had just opened in 1917 but was struggling financially. Lakeside had one 18-hole golf course designed by Wilfrid Reid, but following additional land purchases the club decided to replace it with two courses. These were designed by Willie Watson, a well-known Scottish architect, and the Lake and Ocean courses opened in 1924. The Ocean course was shortly thereafter damaged by landslides, and Sam Whiting (who had constructed the two courses, and would remain as superintendent until 1954) remodeled and rebuilt both courses in 1927. In 1953, the Lake course was lengthened by Robert Trent Jones in preparation for the 1955 U.S.Open.
Jones returned to prepare the course for the 1966 U.S. Open and completely rebuilt the par 3 8th hole. He also lengthened a number of holes and removed dozens of sand bunkers including fairway bunkers on #4, #9, #10, #11, #14, #16, #17 and #18.
In advance of the 1998 U.S. Open, under the direction of Tom Weiskopf, the 15th green was rebuilt and some additional length was added in particular a new multi-tee complex on the 12th hole.
The Lake Course was lengthened further in preparation for the 2007 U.S. Amateur. Architect Bill Love directed these design enhancements -- forty yards added to the par 4 2nd hole. A new tee constructed on the par 3 3rd, which added 30 yards. The par 4 5th, once 457 yards, lengthened to over 500 yards from a new back tee, and the lengthening of the par 4 12th .
The next major scheduled for the Lake Course is the 2012 U.S. Open and additional changes to the design are underway, which include rebuilding all 18 greens to USGA specifications and changes to the 7th and 8th and 15th holes. The par 3 8th hole will be moved to the right of its present location which will turn a 137-yard par-3 into a much longer hole and will allow the 7th green to be pushed back and re-contoured. Several other holes will be lengthened and the 15th green will also be re-contoured. These changes are expected to be completed by June of 2009.
