Good day, 

I am currently working on a thesis focused on developing a predictive model for algal blooms in Laguna Lake. 

As part of our study, I am seeking historical data, particularly from 2013 to 2023, regarding the water inflows and outflows in Laguna Lake. Data about the water flows in every tributary stations in the lake would be very helpful.

Thank you for your assistance. I look forward to your response.
