I spoke with Blake Schaeffer, and this is what he told me:

“The highly reflective surface of land compared to that of water causes error flagging of remotely sensed water quality data at the coastline. Light contamination from land, bottom reflectance and the optical complexity of waters in estuaries and inland waters typically confound the derivation of remote sensing products. Methods developed with ocean color satellites such as MODIS, MERIS and SeaWiFS have demonstrated some success for deriving water quality products in estuaries and inland waters, but most of the focus has been on open ocean waters.”

Several of scientists have been doing it for years! Numerous water bodies are considered impaired and have TMDLs created for them, but there is an obvious lack of monitoring and adequate measurements being implemented. Instead of taking one sample from an impaired water body every month or so (and pay for the lab costs) why not receive more consistent sampling, with a much denser net of measurements being taken, all by satellite?
