17. Conclusions Data for all lakes was well within state standards (where applicable) Water Quality in 2011 so far is much better than in 2010 in most locations Historically, water quality increases as you move south to north. But with nutrient data it appears that the Nitrogen levels in the Inverness has been better than the Hernando Pool.
