Give it sometime it'll fill to the top with a good downpour then you'll know what you got going on or it'll dry out and you'll find a wet spot on the back of the dam then you'll know you have a leak.. Kinda in a play it by ear stage.. Did you core the dam?

I believe in catch and release. I catch then release to the grease..
