ABSTRACIAn ecological and recreational use survey was made of the Luxapalila River in Mississippi. This study was made before channelization work was started by the Army Corps of Engineers. A follow‐up study is planned after channelization work is completed.Four stations were located along a 10.5 mile stretch of river where certain chemical and biological measurements were taken during the four seasons of the year.The results of this study revealed that the river is an unpolluted, biologically productive waterway relatively high in chemical constituents. Eleven families and 37 different species of fish were collected. Biomass measurements of standing crops of invertebrates ranged from a low of 0.11 grams oven dry weight per square meter to a high of 18.89 grams per square meter, with larger biomass collected from eddy areas than from riffle areas.A survey of recreational use of the river indicated relatively light use was made of the river. Fishing was the major use followed by swimmin
