Basics
The project seeks to measure the mechanisms and the efficiency of fine particle removal from urban stormwater using floodplains. The project is based in the Cold Creek/Trout Creek floodplain, and utilizes the Cattlemans detention basin and the floodplain immediately downstream of it. The goals of the project are to (1) quantify the effects of gravitational settling and biofilm processes in the removal of very fine (<20 micron) particles from urban stormwater and to (2) determine the elemental composition of both the stormwater itself and the particulate material to assess the potential for negative impacts to the resident floodplain biota and their food webs.

Threshold Categories
-
The long-term decline of Lake Tahoe’s clarity is the focus of a recently developed Total Maximum Daily Load (TMDL) program. Though not yet fully implemented, research in support of the TMDL program has shown that fine, inorganic soil particles (< 20 microns diameter) are the primary cause of this decline.

| 08/23/2017 6:59 AM | Kiara Cuerpo-Hadsall | Objectives: This study measured the ability of a stormwater detention basin and associated floodplain to remove sediment from stormwater runoff. Primary constituents measured were: flow, total suspended solids (TSS), the inorganic fraction of TSS, fine particle concentration (FSP) for particles 16 µm, and turbidity. |

| 08/23/2017 6:59 AM | Kiara Cuerpo-Hadsall | Findings: • This study measured the ability of a stormwater detention basin (Cattleman’s Basin on Trout Creek) and associated floodplain to remove sediment from stormwater runoff. Primary constituents measured were: flow, total suspended solids (TSS), the inorganic fraction of TSS, fine particle concentration (FSP) for particles 16 µm, and turbidity. • Median inflow, basin outflow and floodplain event mean concentrations were: TSS (mg/L): 54.4, 9.27, 21.6; FSP (#/mL): 2.57 x 106, 7.34 x 105, 6.56 x 105; inorganics (mg/L): 39.22, 3.94, 12.46; and turbidity (NTU): 82.05, 15.22, 29.95, respectively. • Cattleman’s Detention Basin provided significant reductions of total loads of all constituents. • Through the entire system, basin and floodplain, only fine particle concentrations showed a significant decrease. • The basin removed fine particles at similar rates, by mass, as TSS and the floodplain coarsened the particle size distribution. The percent-by-mass of fine particles was 29 for the influent, 31 for the basin effluent and 21 for the floodplain. |

| 08/23/2017 6:21 AM | Kiara Cuerpo-Hadsall | Management Implications: The basin is successfully removing fine particles from stormwater runoff. Extrapolating from the data collected, the basin is estimated to remove a total of 4.4 x 1016 particles annually; a little over 2% of the reductions El Dorado County is required to meet in the TMDL. Considering this facility is only treating an 11.2-acre drainage basin, this is a significant amount of removal. |
