3c Phosphorus limited based on a<br />

TN/TP median <strong>of</strong> 41 (97 values)<br />

during the PP and a median <strong>of</strong> 37<br />

(42 values) during the VP. PP - 0<br />

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

TSI means exceeded 60. 33 TN<br />

values, median 0.57 mg/L . 85 TP<br />

values, median 0.02 mg/L. Need to<br />

continue to investigate a more<br />

appropriate TSI threshold for the<br />

lakes in the Orlando Ridge area.<br />

3c PP - 12/31 values below DO<br />

criterion. VP - 8/8 values below DO<br />

criterion.<br />
