As of this posting the snow pack for the Sierra Nevada mountains is at 51% of normal (CDEC). What does that mean for the wilderness? It is hard to say really. If California continues to have normal average weather allowing the snow to melt at the usual rate, then the summer season may not be too bad. If it stays colder than normal, then it may improve by delaying snowmelt/runoff and prolong water flow in the creeks.
For those adventuring out this summer, plan on rely on perennial streams (ones that flow yearly on a regular basis) to supply your water needs. Other streams that are considered intermittent (seasonally) and ephemeral (flow during runoff) may not be dependable this season. If you are visiting a lake, make sure it is a good size like or supplied with water further above. Most importantly, become familiar with the area you are going to travel. Make sure to call the local Forest Service district office to get the latest conditions of trails and stream flow. Â They may be able to tell you which creeks, regardless if they show up on a map, are really dependable.
