shallowness of the flood delta there. It was not determined whether 

 eelgrass grows north of the Little River bridge. 



In contrast, the bed by Barneys Joy (DABJl) grows in a high 

 energy, well flushed, coarse sand environment, to 1.2 m MLW. This bed 

 was more robust and had greater biomass (shoot density > 400 m~^, 190 g 

 dry wt m~^ ; n=4, se=10) . 



South of the channel at Potomska Pt . is a large sand flat. 

 Eelgrass may grow at the south-most deep edge of this feature, but no 

 beds could be identified from either the photographs or field visits. 

 Eelgrass beds visible on photographs of the north side of Deep Point the 

 during early 1970's disappeared because of erosion in that area in 1978. 



Offshore from Aliens Pond and Barneys Joy, wave action is strong 

 and submerged vegetation could not be discerned on photographs. The 

 bottom is covered with large boulders, but it is likely some eelgrass 

 grows there, although its extant is unknown. 



Mishaum Pt. has a large boulder field to its west, and eelgrass is 

 extensive here beginning at 0.6 m MLW among the rocks. Eelgrass may 

 also grow along the southeastern and southwestern shores of Mishaum Pt., 

 but this area was not field investigated and the sharp slope of the 

 bottom makes interpretation of the photographs difficult. 



The beds indicated in Salters Pt. Pond may be algae. Whether they 

 are algae or eelgrass, the vegetation is less abundant in the 1981 

 photograph than the 1970's photographs. Outside of Salters Point Pond 

 is a dense eelgrass bed in which a transect was run. Biomass was 160 g 

 dry wt m"2, density was 350 m"^, and leaf canopy exceeds 1.2 m.
