In semiarid, snowmelt-driven, irrigation-regulated Little Bear River watershed northern Utah, situ water quality measurements were recorded conjunction periodic chemistry sampling. Site-specific relationships developed using turbidity as a surrogate TP TSS at two monitoring locations. Methods are presented employing censored data investigating categorical explanatory variables (e.g., hydrologic conditions). Turbidity was significant variable both sites, differ characteristics. The relationship between stronger upper site where is predominantly particulate. At varied spring snowmelt base flow conditions while consistent across hydrological conditions. This approach enables calculation time series concentrations previously unavailable traditional approaches. These methods broad application situations that require accurate characterization fluxes these constituents over range
