A question of great importance in managing water storages is that of where 
does water come from when withdrawals are made for town supply, irrigation or 
power generation? Many results about the steady-state flow induced during 
withdrawal from a stratified reservoir are known.  Much less is known about 
the flow generated in the initial moments after the withdrawal begins.  
In this talk I will outline some results that show the initial flow 
(computed both numerically and analytically) and how it helps to place the 
various steady flow results and experimental results in context.
