A simple calculation based on typical continental geothermal heat fluxes show that the energy is sufficient to melt millimetres to a centimetre of basal ice. Consider that this melting occurs during the course for a year and the volume of water will be the melt rate multiplied by the basal ice-ground contact area of the glacier and the numbers will show that the runoff will be minuscule. Hence such contributions are generally not comparable to those produced by the "base flow" from ground and glacier aquifers.

The following paper provides a thorough description of storage of water in glaciers:

Jansson, P., Hock, R. and Schneider, T., 2003. The concept of glacier storage -- A review. Journal of Hydrology. 282 (1-4), 116-129.

A large volume of literature on glacier hydrology and runoff can be found in Journal of Glaciology.
