Total annual loading (point and nonpoint source) of total phosphorus, total nitrogen and total suspended solids fro as determined by FLUX, during the diagnostic study of Lewis Smith Lake, November 1994 through October 1995 C 15
(31.4% and 30.5%, respectively). Rock and Ryan Creeks contributed a significant portion of the TN load (33.0% and 25.6%, respectively). Total monthly loading ofTP, TN and TSS was also estimated using FLUX (Figures 9-2, 9-3, 9-4, 9-5, 9-6 and 9-7). Loading estimate patterns for all variables were similar to total monthly discharge patterns for Rock Creek and Sipsey Fork. TP, TN and TSS were highest in February at these stations. Estimated loading patterns at the other three creeks were more variable. Total monthly loading ofTP in Ryan Creek preceded the total monthly discharge by peaking in February, while total monthly discharge peaked in March and April. At Crooked Creek, total monthly TP loading and total monthly discharge were similar, with the highest values in March and April. At Clear Creek total monthly TP peaked in March and declined rapidly in April, while total monthly discharge peaked and remained fairly constant during March and April. Total monthly TN loading was highest in March and April at Crooked and Ryan creeks as were the total monthly discharges. In Clear Creek total monthly TN peaked in March and then declined in April, while total monthly discharge peaked and remained fairly constant during March and April. Total monthly TSS loading peak at Ryan Creek preceded the total monthly discharge by peaking in February, while total monthly discharge peaked in March and April. At Crooked Creek, total monthly TSS loading increased through March and peaked in April, while total monthly discharge peaked in March and held constant during April. Total monthly TSS loading and total monthly discharge patterns were similar at Clear Creek. Both peaked during March and April. 45
