At Station 10, dissolved oxygen exceeded State standards 4% during the 74 separate water quality sampling events at the surface and 25% of the 73 times sampled at the bottom between January 1996 and November 2008. All samples reflected a marine environment; turbidity levels were within State standards at the surface and exceeded State standards during 1% of the times sampled at the bottom; and mean clarity was 39%. Ammonia levels were above levels that could impact sensitive species during 17% of the sampling events at the surface and 19% at the bottom. Nitrite, nitrate and DIN were within tolerances and orthophosphorus concentrations indicated that the station exceeded guideline criteria during 25% of the times sampled at the surface and 74% of the times sampled at the bottom. Iron was within State standards at the surface and exceeded State standards during 1% of the bottom samples (Appendices A and B). At Station 11, dissolved oxygen was below State standards during 5% of the 74 separate water quality sampling events at the surface between January 1996 and November 2008. All samples reflected a marine environment; turbidity levels were within State standards; and mean clarity was 84%. Ammonia levels were above levels that could impact sensitive species during 28% of the sampling events. Nitrite, nitrate and DIN were within tolerances and orthophosphorus concentrations indicated that the station exceeded guideline criteria during 25% of the times sampled. Iron was within State standards during the times sampled (Appendices A and B). At Station 12, dissolved oxygen was below State standards during 42% of the 74 separate water quality sampling events at the surface between January 1996 and November 2008. All samples reflected a marine environment; turbidity levels exceeded State standards during 1% of the times sampled; and mean clarity was 58%. Ammonia levels were above levels that could impact sensitive species during 42% of the sampling events. Nitrite, nitrate and DIN were within
