Description Station Latitude Longitude
SE Branch Homosassa River 1 N 28° 47.839' W 82° 35.335'
Blue Water 2 N 28° 47.924' W 82° 35.432'
Blue Water Point Canal 3 N 28° 47.809' W 82° 35.574'
Jefferson Point Canal 4 N 28° 48.052' W 82° 35.897'
Halls River Bridge 5 N 28° 48.096' W 82° 36.166'


NOTE: Total N and P testing is now sampled every 2 months









Note: 2 very high peaks of Chlorophyll (640, 630 µg/L ) sampled at Jefferson Canal (Point 4) on Aug 6, 2007 and June 4, 2008 were outside of the chlorophyll graph window. They have been deleted. The nutrient source should be investigated.

The almost Chlorophyll free samples at the Bluewater (2) make sense. The water is discharging directly from the aquifer and has not had time to "build" Chlorophyll with the rather high total N and P concentration contained in the aquifer.

The USGS / SWFWMD have been recording the daily water discharge at Homosassa Springs between 1996 and December, 2007. They have also recorded the conductance of the water between July, 2004 and December, 2007.

No measurements are available for the year 2008.

The USGS / SWFWMD resumed monitoring both discharge and conductance again on January, 2009. The monitoring station is located at Lat N 28° 47' 58" and Long W 82° 35' 20". All available data is displayed below. You will notice that both graphs are displayed in different scale format. But the trend is rather obvious. The quantity of Water discharged has definitely been reduced since 1996.

The conductance measured in MicroSiemens / cm ( electric current passing 1 cm through the water) is a clear indicator that salinity or other soluble contaminants have considerably increased.

The increase in conductans and decrease in daily discharge of water could very likely signal saltwater intrusion. Long time residents along the Homosassa River have noticed a greater barnacle buildup near the Bluewater springs.



Note: Both tables are presented vertically in log scale and horizontally compressed.   

Note: Starting in 2009, column grids represent 2 month daily averaged daily data collection. No data has been collected in 2008.



  


Note that data prior to 2008 uses a different vertical scale. No data is available for 2008. The new scale format since January, 2009 on both X and Y axes is a great improvement.
