About this dataYearly means for each water year (October through September), from USGS daily records. Out of the lake: the St. Lucie Canal below Port Mayaca, S-308 (02276877); below zero, more water ran back into the lake than out. Into the estuary: the St. Lucie Lock, S-80 (02277000 through 2003, then 02276998 from 2017). USGS didn't gauge Port Mayaca from 1953 to 1981 or the lock from 2004 to 2016, and years missing more than a month of days are left out.
