Keywords: AnnAGNPS, rice/crawfish management practices, field pond feature in AnnAGNPS. Impact of effluent of rice/crawfish pond on water quality
Rice and crawfish farming are important agricultural management practices in the state of Louisiana. The
effluent from rice/crawfish ponds is an environmental concern because of high sediment and nutrient concentrations.
Watershed models are frequently used for watershed evaluations for Best Management Practices (BMPs)
recommendations and Total Maximum Daily Loading (TMDL) allocation. However, current available models used for
TMDLs development such as BASIN, SWAT and AGNPS do not have the capability of simulating the impact of
rice/crawfish ponds on the receiving water bodies.
