Government Cut: tide and current notes
Government Cut is one of the 20 inlets and passes Anglrithm measures runs from, in the Broward and Miami region. This page sets out the public facts about its water: the NOAA tide gauges around it and how their tides run, what is known about its current, and the structure outside it.
How the tide runs here
4 NOAA tide gauges sit within 6 nm of the inlet. Highs are timed against Government Cut (8723178), the reference for the Atlantic coast and the Keys.
- Government Cut CO-OPS 8723178ocean side, 0.0 nmMean range 2.3 ft; highs the reference gauge.
- Fishermans Channel CO-OPS 8723155Biscayne Bay, 2.1 nmMean range 2.0 ft; highs about 34 minutes after Government Cut.
- Virginia Key CO-OPS 8723214Biscayne Bay, 2.6 nmMean range 2.0 ft; highs about 24 minutes after Government Cut.
- Key Biscayne YC CO-OPS 8723232Biscayne Bay, 4.5 nmMean range 1.9 ft; highs about 44 minutes after Government Cut.
The high at Fishermans Channel (Biscayne Bay) comes about 34 minutes after the high at Government Cut on the ocean side, with a range of 2.0 ft against 2.3 ft outside. The water in the inlet moves between the two.
For the water at the mouth Anglrithm reads Government Cut (8723178), 0.0 nm away: a gauge in the same tidal water, never one inside an inlet, on the Intracoastal or up a river, because those run late against the water outside.
From NOAA CO-OPS tide predictions, October 4, 2026 to November 15, 2026: the mean range between successive highs and lows, and the median time from the high at Government Cut to the high at each gauge. A description of this inlet's tide, not a tide table.
Current
NOAA publishes current predictions for this inlet at station MIH0901. Anglrithm reads them into the inlet current lane on the app's Weather day strip; this page does not give the strength or timing of the ebb and flood, so check that lane or NOAA's current predictions before you run the inlet.
Wind blowing against the current stands the seas up: shorter, steeper and more likely to break than the same wind over slack water, which decides how a drift sets up and how long a day stays fishable. That is physics about the water, not evidence about the fish; no study we found ties it to catch.
U.S. Coast Pilot 4, Chapter 3 (opposing wind and current on the Gulf Stream: sharply higher, steeper seas that can break; mechanism only). No catch study found.
Within 10 nm
243 of the 2,153 wrecks and reefs in the structure file lie within 10 nm of the inlet, from FWC artificial reef program, Miami-Dade County DERM and NOAA Office of Coast Survey charts.

What the studies say about this water
A study that names this inlet, in our own words, with its source. Guidance beside the score, never in it.
The study: Dobbelaere et al. 2024
Plumes from Miami and Broward inlets drift mostly north but also reach tens of kilometers south, worst in the wet season.
SLIM ocean model, September 2018 to August 2021, releasing inlet water from Government Cut, Haulover, Port Everglades and Hillsboro using SFWMD flows. Plumes ran mostly north but had southern footprints of tens of km. Government Cut had a bigger footprint and load than the other inlets modeled. Concentrations were higher in the wet season, May to October. Model only.
