New: Pull Site Data. Tap one button on a new sample point (or on an existing plot’s Summary tab) to auto-fill PLSS, soil map unit, NWI classification, and MLRA from your current GPS location - pulled from public USDA, USFWS, and BLM data services. New: Terms & Conditions. A one-time acceptance screen on first launch, also available anytime from the Help tab. Fixed: Hydric soil wasn’t registering “Yes” in the Summary or PDF when only a Problematic Hydric Soil Indicator (including “Other”) was checked. Fixed: The keyboard was covering Remarks fields instead of scrolling them into view. Improved: Vegetation species and soil horizons can now be tapped to edit in place, instead of only delete-and-re-enter. Duplicating a plot now offers to open the copy directly.
Aqualf - Midwest Region Wetland Determination Data Forms Aqualf replaces the paper USACE Midwest Region Wetland Determination Data Form (ENG FORM 6116-7, v2.0) with a structured, on-device workflow built for field work - rain, mud, and spotty signal included. Built for the field, not just the office. Create a project, add sample points, and fill out Hydrology, Vegetation, Soils, and Summary - all from your phone. Dominance test, prevalence index, FAC-neutral test, and hydric soil indicators calculate automatically as you enter data, so you see your determination forming in real time instead of doing math back at your truck. Pull Site Data At a sample point, tap “Pull Site Data” to auto-suggest PLSS location, soil map unit, NWI classification, and MLRA from your GPS coordinates - sourced from BLM, USFWS, and USDA public data services. Built on the current standard Hydric soil indicators follow USDA-NRCS Field Indicators of Hydric Soils, Version 9.3 (2026). Hydrology indicators follow the USACE Midwest Region Regional Supplement, Version 2.0. Export a clean PDF Generate a form that mirrors the official USACE layout, ready to attach to a Joint Permit Application or a project report - no transcribing field notes later. Your data stays yours No account, no Aqualf server, no telemetry. Project and plot data lives in local storage on your device. The only thing that ever leaves is a GPS coordinate, and only when you tap Pull Site Data. Built independently by a Professional Wetland Scientist. Not affiliated with or endorsed by USACE, USDA-NRCS, or any other agency - a tool to speed up fieldwork, not a replacement for professional judgment or the official data form where one is required.
