I n t he midwest there are many man-made impoundments which experience severe sediment-related problems. Sediment Oxygen Demand (SOD) measurements have g rea t p r a c t i c a l u t i l i t y f o r t he management o f sediment-impacted lakes f o r which sediment dredging o r ae ra t i on1 d e s t r a t i f i c a t i o n schemes represent v i a b l e rehab i l i t a t i o n schemes. The r e p o r t summarizes a f i f teen-month study o f the phenomenon o f SOD i n two shallow I l l i n o i s impoundments. Both lakes have served as p u b l i c water suppl ies and experienced s i g n i f i c a n t water q u a l i t y problems associated w i t h sediment accumulation o r seasonal anoxia. The aims o f the i n v e s t i g a t i o n were t o i d e n t i f y the p r i n c i p a l components o f t he SOD and t o develop an opt imized SOD procedure. B r i e f l y , batch resp i romet r i c measurements o f SOD were found t o be most d iagnost ic o f oxygen dep le t i on due t o sediment resuspension o r disturbance.
