MLLW definition

MLLW means mean lower low water. “MSD” means marine sanitation device.
MLLW means mean lower low water. mg/l means milligrams per liter. Mixing zone means the area adjacent to a discharge or activity in the water where a receiving water may not meet all the water quality standards; wastes and water are given an area to mix so Monthly average means the average of daily discharges over a monitoring MSD means marine sanitation device.
MLLW or "mean lower low water" means a tidal datum or level which is calculated by determining the mean of the height of the lower of the two daily low tides over a 19-year period."

Examples of MLLW in a sentence

  • For marine nearshore areas, critical habitat extends offshore to a depth of 33 feet relative to the mean lower low-water line (MLLW) (average of all the lower low-water heights of the two daily tidal levels).

  • This area between MHHW and minus 10 MLLW is considered the habitat most consistently used by bull trout in marine waters based on known use, forage fish availability, and ongoing migration studies, and captures geological and ecological processes important to maintaining these habitats.

  • Water depths on the leasehold range from between -4.5 feet and approximately -24 feet at MLLW.

  • The proposed site is located away from any red mangroves and in waters deeper than 36” in MLLW, so as to avoid any impacts to the essential features of smalltooth sawfish critical habitat.

  • To meet the projected 50-year sea-level rise, the new gates, the rebuilt Gate E, and pedestrian areas will be reconstructed at 14.5 feet above MLLW.

  • Mussel cages will be anchored into the substrate and/or secured to fixed objects in the intertidal environment at each site at approximately zero to -1.5 feet mean lower low water (MLLW).

  • Currently, Gate E is at an elevation of around 11.8 feet above mean lower low water (MLLW).

  • Drawings will indicate a final dredge elevation of -54 MLLW for this phase of the project.

  • The City shall maintain a depth of approximately minus 38 feet MLLW in the berthing area.

  • Bridge piers or fill placed in the littoral zone (the area between mean higher high water [MHHW] and about -20 ft MLLW) would cover and destroy existing sedentary biota that includes commercially or recreationally harvestable clams and mussels.
