A free, one-person project — the data is public, the domain and upkeep aren’t. If the tide times saved you a wasted trip to the ramp, you can toss a few bucks in the tip jar. No account needed; the site stays free either way.

A ping as the water reaches its next high and its next low, or a little before. Heads-up on changes
When tomorrow’s peak will be noticeably bigger or smaller than today’s. Above or below a level
When the water climbs past or drops past a level you set, in feet vs this week’s average (0.0 = a normal moment this week). Leave one empty to use just the other.

Alerts arrive as normal phone or desktop notifications, checked about every 10 minutes as new sensor data lands. Each spot you add keeps its own settings; pick another spot on the main page and come back here to add it too.

Note (optional)

✚ Depth mark at

A mark is one fixed reference where readings are always taken: the toe of a ramp, a dock piling, the tip of a sandbar. Readings from everyone at this mark build its own depth curve.

Name Exactly where the reading is taken Landmarks, bottom to top (optional, one per line)

With landmarks, people can report “water is at the first joint” instead of measuring. The heights work themselves out from readings; typing them just speeds that up.

When Note (optional)

The time matters most: the river moves several feet a day, so the reading is matched to the level the sensors say this spot had at that moment.

◎ Landmarks on the photo

Tap where each landmark meets the water line, bottom of the ladder first. Tap a landmark’s chip to move it. With two or more placed, anyone can report a reading by tapping the water line, and the page can draw where the water is on this photo.
