Flood & low finder

🌊 Biggest flood tides at Prisoners Point this month: Aug 5, Aug 6, Aug 8, Aug 9, Aug 10, Aug 11, Aug 12, Aug 13. 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 Prisoners Point this month: Aug 1, Aug 10, Aug 11, Aug 12, Aug 13, Aug 14. These drain the flats and expose the oyster rock — prime for sight-fishing and clamming.
