@PhilMiller Here is the BMI development of the USGS water level gauge data provider for you to test and evaluate SCHISM in a fully coupled NextGen formulation. I'll be happy to address any questions or concerns you may have. Keep in mind that I'm only proposing a new repository potential for "BMI water level data providers" but I'll be happy to discuss this accordingly with how the model engine team wants to move forward with that data provider integration into the NextGen framework.
