Is it better for a water table to get snow or rain?

    It somewhat depends on the specifc watershed, soil type and bedrock geology, however, genearlly speaking snow will raise the water table for longer than rain will. Once the ground is saturated, rain will just continue to run off the surface, and no longer impact the local water table. However if in that same watershed, the precipitation falls as snow and it does not melt immediately then it will have a delayed impact on the water table, raising the water table later in the spring when the snow melts. In many seasonally arid mountainous places, the water table is dependent on snow melt through the dry season. So if that snow falls as rain, if temperatures rise, than those regions will not have the more continued water source that both the human and ecological communities depend on.
