I'm looking for a calculator or guide that would suggest how much rainwater could be collected in Mid-summer or the month with the highest irrigation demand. We have a 3000 gallon cistern in the Pacific northwest. I would guess that the tank would be considered dry in the summer but it would be great to confirm. Thank you for any advice.

Karin, I don't know of a single good resource on this. I would ideally consult with an engineer.

Karin,
Contech's rainwater harvesting runoff reduction calculator will help you with monthly supply/demand optimization:

I am not affiliated with Contech, but I like this tool. I hope it helps you. Feel free to contact me to discuss further.
