Unfortunately the drought is caused almost as much by the over consumption of water as the lack of rain. This will help in the short term to get levels back up, but we're still taking more than nature is putting in.

It's ultimately a temporary reprieve that'll help with water supply for this year and maybe a ripple effect into next year depending on how much melts. The issue is prolonged drought plus overconsumption of water resources has depleted the 'stockpile' of snowpack that usually accumulates year over year, as well as the groundwater reserves. What the state needs is at least several winters with rain/snowfall like what we're getting this winter.
