All boat ramps are still closed. But with talks from the TRPA, they are planning to open to Tahoe only boats in the near future. These are mainly local boat owners that have had their vessel certified and inspected previously to fish or recreate on Tahoe only.  If you are planning on bringing your boat up from out of the area. You will not be allowed to launch. Note, this is in the planning stage and ramps are not open as of this date.
