The survey and experimental research methods to assess water quality assessment and soil sedimentary deposition through the floating basket aquacultures of the Chi River in Northeast region, Thailand through the sub-section Mahasarakham Province flowed and the collecting determination data along the 122-length kilometers at six waterway stations, and six soil sedimentary points for the scheduled times in three seasons from January to July 2017 under the fish floating basket aquacultures were measured and assessed to the key parameters: pH, Dissolved Oxygen (DO), Oxygen used in Biochemical Oxygen Demand (BOD), Nitrate (NO3--N) and Orthophosphate (PO43-) through utilizing the efficiency of water. The analyzing parameter data indicates the mean averages of temperature ranged 24.06–26.93oC, transparency as 16.66–46.33 cm., pH value ranged 6.76–7.30, DO quantity was 4.24–4.89 mg/L., BOD was 2.86–4.03 mg/L., NO3-–N was 0.48–0.90 mg/L., and PO43- was 0.24–0.47 mg/L, for assessing the determination of the river water quality. The soil sediments’ types were deposited that composed of sandy loam, sand, loam, and clay loam at six stations. The mean averages for each parameter; pH value was 5.27–6.73, the EC was 0.06–0.41 ms/cm, OM value as 0.02 – 1.36 %, nitrogen quantity was 0.00-0.06%, and available PO43- was 28.12–158.19 mg/kg. There also found that the comparisons between each parameter from six sampling points are differentiated at the level of .05, significantly.
