4. Inflow monitoring: A supplemental monitoring program will be conducted by ERD to <br />evaluate the hydrologic and chemical characteristics of significant inflows into and between <br />the four lakes. Potential locations for the inflow monitoring program are indicated on <br />Figure 1. During each monitoring event, field measurements of discharge will be conducted <br />at 6 monitoring sites using the velocity/cross-sectional area method as outlined by USGS. <br />Surface water samples will be collected at two of the six monitoring sites and analyzed in <br />the ERD research laboratory for the following parameters ($143/sample): <br />a. pH ($4.50) g. Total Nitrogen ($25) <br />b. Specific Conductivity ($5) h. Orthophosphorus (SRP) ($10) <br />C. Alkalinity ($10) i. Particulate Phosphorus ($15) <br />d. Ammonia ($10) j. Total Phosphorus ($15) <br />e. NO,, (nitrite + nitrate) ($12) k. Total Suspended Solids (TSS) ($10) <br />f. Particulate Nitrogen ($20) 1. Turbidity ($6.50) <br />The proposed supplemental monitoring program will assist in establishing hydrologic and <br />nutrient loadings from significant inflows into and between the four lakes. For budget <br />purposes, 16 inflow water samples are proposed. <br />Figure 1.
