3c Phosphorus limited. PP - 0 TSI<br />

annual means exceed threshold <strong>of</strong><br />

60. VP - 0 TSI annual means<br />

exceed threshold <strong>of</strong> 60. 350 TN<br />

values, median 0.75 mg/L, mean<br />

0.76 mg/L. 30 TP values, median<br />

0.046 mg/L, mean 0.16 mg/L. Need<br />

to continue to investigate a more<br />

appropriate TSI threshold for the<br />

lakes in the Orlando Ridge area.<br />
