And a new app icon to go along with that. ### 1.0.15 — 2025-03-19 Thanks for using and updating Lock Status! The data feed from the US Army Corps of Engineers was broken, so the app now uses an updated data feed from the USACE. Unfortunately, this new data feed does not provide the MMSI of vessels travelling through locks, so direct links to MarineTraffic for vessels have been removed. If the USACE starts providing this information again, I will add in the links to MarineTraffic! ### 1.0.13 — 2022-06-07 Fixing some broken URLs, so data was not loading properly! ### 1.0.10 — 2021-10-09 Fixed a bug relating to the retrieval of lock stoppages/closures provided by the USACE. Added the Chiquita Lock in Cape Coral, FL. ### 1.0.9 — 2021-09-28 Search function! Requires iOS/iPadOS 15. Added support for locks that aren't operated by USACE in order to provide contact information/hours/etc. for other locks. The first lock added is Tenney Lock near Madison, WI. If anyone has other locks that they would like to see added, don't hesitate to email the developer using the "Email Andrew" link in the info. Tap the info button on the first screen to find that link! Any other feedback is always welcome! ## Apps similar to Lock Status | App | Rating | Price | Category | | --- | --- | --- | --- | | [Pumpout Nav](https://appshunter.io/ios/app/pumpout-nav/id1148752109) | 4.5 (88) | Free | Navigation | | [Nebo - Boat Logging Made Easy.](https://appshunter.io/ios/app/nebo-boat-logging-made-easy/id1105306790) | 4.1 (34) | Free | Navigation | | [Coastal Explorer](https://appshunter.io/ios/app/coastal-explorer/id1452017231) | 2.7 (14) | Free | Navigation | | [AGLCA](https://appshunter.io/ios/app/aglca/id6476233488) | 4.9 (307) | Free | Navigation | | [Waterway Guide](https://appshunter.io/ios/app/waterway-guide/id1551794976) | 4.7 (2,768) | Free | Navigation | | [Ditch: Boat Navigation](https://appshunter.io/ios/app/ditch-boat-navigation/id1667064532) | 3.9 (22) | Free | Navigation | ## More apps by Andrew Thom - [Lansing Ferry](https://appshunter.io/ios/app/lansing-ferry/id6759680246) All apps by Andrew Thom: https://appshunter.io/developer/1231883383 ## Related topics [tombigbee](https://appshunter.io/ios/topics/tombigbee) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
