Flood & low finder

🌊 Biggest flood tides at Little Harbor this month: Aug 9, Aug 10, Aug 11, Aug 12, Aug 13, Aug 14, Aug 15, Aug 16. These spring highs push water up into the grass and over the oyster rock — prime for poling into flooded marsh for tailing reds.

🔻 Negative (minus) low tides at Little Harbor this month: Aug 11, Aug 12, Aug 13, Aug 14, Aug 15, Aug 29, Aug 30, Aug 31. These drain the flats and expose the oyster rock — prime for sight-fishing and clamming.
