range of values measured was 8.2 8.4 at all stations except Stations 6 10. At Stations 6 and 8 the range was from 8.1 to 8.4; at Station 9, 8.1 to 8.5 and at Station 10, 8.0 to 8.4. Water Clarity Water clarity is the single most variable water quality indicator in the Benner Ray-Lagoon area. Basically, all of Benner Bay, and to a lesser extent the channels from Benner Bay weRt to the Lagoon and southeast to Jersey Bay, have poor water clarity and color. In these areas the bottom is typically not visible. Secchi depth is as little as 0.25 meters, the water contains dispersed fine particulate matter. and the color is brown, greyish brown or greenish brown. Quantitative data for water clarity and color are in Tables 4, 5, 6, 7 and 14. The bottom is never visible at Stations 6, 7, 0 and 9 in Denner Bay even though the depth at all these points is less than 2.5 meters. In contrast, the bottom could always be seen at Stations 3 and 5 and it was (except following mud-laden flood run-off) always visible at Stations 1, 4, 10 and 11 (Figure 4). Following flooding on May 9th to 10th, Secchi depths were first reduced at those stations nearest the sites of Page 15
