Thanks Pete. I got your idea. The difference btw net inflow toward the lake and the rate of water removed from it through BC was 1.5%, which is pretty good I guess.

I'm looking to see the contribution of flow from each of 5 different aquifers in my model to a lake (Model flow toward the lake) by reading the Dirichlet BC Rate-out. But Feflow can only shows the results for the whole model domain or a portion of it (i.e. a specific node/element selection). When I select the whole area of the model and save it as the Node/Element selection #1 and use it to calculate the budget, the result is exactly the same as the selection for the whole model domain (i.e. all layers). Then I assume I cannot calculate the flow budget of each layer individually! Is that correct?

I know the way to track the concentration of different species/chemistry into an OBS point but it doesn't work for total flow. I need to know the amount of flow coming in an area, not the concentration or particle tracking.

Any suggestion is appreciated.
