2. Topo maps come in two sizes 7.5' (1" = 0.38 mi. 1:24,000) (these are more detailed and recommended for hikers) and 15' (1" = 0.99 mi. 1:62,500)
They were produced by the United States Geological Survey (USGS) (topomaps.usgs.gov).
Current Versions:
Norden: Revision 2000
Cisco Grove: Photorevised 1979

Note: I couldn't find any map with the correct trail to Flora Lake.

The Lake Tahoe Trail Map at Adventure Maps (adventuremaps.net) Avail. for purchase at CTL. 15 ' [1" = .98 mi.] is very good.

"The Tahoe Sierra", by Jeff Schaffer from Wilderness Press has very good maps also.
