Table V-9 (continued). Chesapeake Bay Program segments and tidal water designated uses where attainment of the instantaneous min¬ 
imum, 1-day mean and 7-day mean dissolved oxygen criteria can be assessed using 30-day mean data or dis¬ 
solved oxygen criteria attainment assessment may require collection and evaluation of data of higher frequency 
than 30-day means.
