BWTF community testing

Mala Ramp is the boat ramp and shore-dive entry point at the north end of Lahaina, popular with divers and snorkelers exploring the wrecks and reef. Check the Community Water Testing section for the sample date, result and full Surfrider report. A sample describes the water collected at that place and time; it does not establish today's water quality. Check the live DOH status above separately.

Why the Readings Run the Way They Do
Boat ramp + post-fire runoff zone

Mala Ramp is a boat ramp and shore-dive entry at the north end of Lahaina. The nearby harbor activity and watershed are part of the setting for Surfrider's community sampling.

A past sample does not establish current bacteria levels or the effect of post-fire runoff. Check its collection date and source report, current DOH advisories and local access updates separately.

🌧️
After Rain — Wait Times
Light rain: 72 hours minimum, then visually verify the water has cleared.
Moderate rain: 4–7 days.
Storm or Kona low: wait until the water returns to clear blue-green visually. Can take 1–2+ weeks in extreme cases.
Testing Coverage

The Hawaii Department of Health does NOT routinely test Mala Ramp (Lahaina). The community-tested readings on this page come from the Surfrider Foundation Blue Water Task Force, a volunteer-led monitoring program run by the Surfrider Maui chapter.

BWTF samples Mala Ramp (Lahaina) monthly using the IDEXX Enterolert method (MPN/100mL), and compares results against the same 130 Beach Action Value DOH uses statewide. See our overview of citizen water-quality testing in Hawaiʻi for the methodology and how BWTF data fits with DOH coverage.

Practical Notes
Where to Enter

Boat ramp + adjacent shoreline. The Mala Wharf wreck is the main draw — historic concrete pier collapsed in storms, now a thriving artificial reef. Strong currents during tidal exchange. Pre-dive briefing essential for the wreck.

When It's at Its Best

Calm summer mornings before trade winds pick up. Slack tide is preferred for the wreck dive. Lahaina is in active rebuilding; the ramp area is open but the surrounding community is recovering.

Getting There

Off Front Street north of central Lahaina, near the harbor. Mala Wharf parking. Several dive operators run charters here — some shore-dive packages include guided tours of the wreck.
