No, unfortunately there is no way to know when the releases will happen, how much water will be released and when the gates will be closed. The best way to gauge it is to know that Lake Pueblo is not allowed to store flood waters. So when there is a large rain you will see a day or three of big water. The last time we had big water the paper had the following story explaining the flows. I hope it helps you make your decision.
Btw, we are expecting more rain later today!
