Snow water equivalent is a measurement of how much liquid is contained in a snowpack. We use these measurements to estimate spring runoff into area lakes and river systems.
As of today, SWE is generally running 70-90% of average around the Tahoe Basin (higher elevation sites are closer to 100%), but only 55-70% for Mono County. While most sites are running below average, there's still time to catch up to the seasonal averages. This does highlight the importance of the last Atmospheric River event where Mono County receive so much snow.

I don't give out specific route information, my belief is that it takes away from the whole adventure spirit of a trip, if you need every inch planned out, you'll have to get that from someone else.

big gradient from San Joaquin (60%) to Kaweah (40%). go south, young person.
Or north, if you're planning ski trips :-D.
The Southern Sierra is always tough to keep snow on. Mt Whitney has no glaciers for a reason, despite being so tall (behind the GWD, far south, arid climate).

Cottonwood Lake #4 looks to already be thawing on the satellite image taken 3-Apr. April was projected to be wet, but NOAA has backed off that prediction. I'd bet the Southern Sierra would be accessible mid-May. Snow will still hang around on north faces high on the crest for a long time, so big passes will still require snow gear.

Given satellite image updates, just might have a late spring one night trip if I can justify the long drive with other explorations on the East Side to hike up the notorious Symmes Creek trail just to the Shepherd notch at 2800 meters where in 2019 I managed a very nice pre-sun rise landscape of Williamson and areas north. Potential for superb atmospheric light given desert clear air days. There may well be snow patches still that can provide water. Best set up to do at short notice just after a late May spring storm to add some fresh decoration on the big peaks.
