A Limnological Investigation of the Relationship between the Navasota River, Texas, and a Selected Floodplain.

Abstract

A limnological investigation of the Navasota River and an adjacent floodplain in Grimes County, south-central Texas, was conducted between January 1971 and September 1971. The study centered on the physicochemical and biological dynamics of events associated with a sudden spring flood (spate). Water samples from the river and the floodplain were analyzed. The early stages of the river rise were found to have higher concentrations of organic materials and other chemical constituents than did the stages that followed. This was attributed to the flushing action of the early stages and the subsequent dilution of runoff water. Rainfall runoff was shown to carry large quantities of nitrate and phosphate into two small ponds on the floodplain. Phosphorus uptake by pond organisms was rapid. (Modified author abstract)
