of approximately 0.05 m2. It is important to remember when interpreting graphs for the benthos that-only one sample was- collected-for:each station at each sample period. Overview of Invertebrate Sample Stations Invertebrate sample stations were established in the study area in .June of 1993 (.Figure 23). A total of 14 stations were. sampled for invertebrates (Table 6). Communities represented by these stations-are: 1) bulrush (4 stations); 2) open water- aquatic (5 stations); 3) flooded willow (1 station); 4) riverine backwater (1 station);-and 5) river, (3 stations). Communities were sampled six times during 1993 on or about the dates of 16 June, l-July, 17 July, 30 July, 13 August, and 18 October. Only :one backwater was selected because it was the only one available in the study area. When stations went dry they were no longer sampled.. Table 6.
