From Zoe Kulakowski (2010, p. 42), Chromophoric Dissolved Organic Carbon Loading of Five Intermittent Streams Recharging Wakulla Springs, Florida: “Wakulla Springs exhibits a duirnal tidal signal that has a forty-five minute delay from the tides at St Marks. Still this response is faster than the tidal signal recorded at the Wakulla River USGS Station approximately one mile down stream from Wakulla Springs (Loper et al 2005). A faster response at the spring vent suggests a significant conduit network to allow the tidal signal to travel 16 kilometers (10 miles) inland and upgradient faster than up the river channel.”
