Quick answer: Every U.S. state's lowest elevation point is documented-most coastal states' lowest points are at sea level, several interior states have river valleys as their low points, and the nation's single lowest recorded elevation is Badwater Basin in Death Valley, California at -282 feet below sea level (below is a sampled table showing each state's low point and elevation).
What counts as a state's lowest point
Lowest points are defined as the point within a state with the smallest elevation above or below mean sea level; for coastal states this is commonly a shoreline at sea level and for interior states it is often the bed of a river or lake.
Notable statistics and historical context
California's Badwater Basin has held the record for the lowest natural point in the contiguous United States since USGS surveys in the 20th century established elevations across Death Valley; its official depth is -282 feet below sea level as recorded in federal topographic datasets.
Colorado's lowest elevation (Arikaree River, ~3,315 ft) is historically remarkable because that "low" point remains higher than the highest points of 18 other states, a fact repeatedly noted in geographic literature since regional mappings in the 19th and 20th centuries.
Several populated places have experienced human impact tied to low elevations: New Orleans' average datum and engineered levee history reflect persistent flood risk where portions of Orleans Parish sit several feet below sea level (commonly cited at around -8 feet for some benchmarks).
Representative table: Lowest point by state (selected examples)
| State | Lowest Point Name | Location (County/area) | Elevation (ft) | Notes |
|---|---|---|---|---|
| California | Badwater Basin | Inyo County | -282 | Lowest natural point in North America. |
| Louisiana | New Orleans (local benchmarks) | Orleans Parish | -8 | Several neighborhoods sit below sea level; complex levee history. |
| Florida | Atlantic/Gulf shoreline | Coastal counties | 0 | Coastal low point at mean sea level; state mean elevation ~100 ft historically cited. |
| Colorado | Arikaree River | Yuma County | 3,315 | Highest "lowest point" of any state. |
| Delaware | Atlantic shoreline | Coastal plain | 0 | Lowest mean and naturally low relief in the mid-Atlantic. |
Full-format quick list (selected grouping)
- Coastal states: Lowest point typically the Atlantic, Pacific or Gulf shoreline at sea level (0 ft).
- Interior states with river low points: Many Midwestern and Plains states list major rivers (Mississippi, Missouri, Ohio) as their low points.
- Below-sea-level exceptions: California (Badwater Basin) and localized human-set benchmarks in places like Louisiana record below-sea-level elevations.
Ordered examples: states with the most extreme low elevations
- California - Badwater Basin, -282 ft (lowest in the U.S.).
- Louisiana - parts of New Orleans below sea level (approx. -8 ft at some benchmarks).
- States at sea level - dozens of states (e.g., Florida, Delaware, New Jersey) have their practical low point at 0 ft where land meets the sea.
- Colorado - Arikaree River, ~3,315 ft (highest of all state low points).
Regional patterns and why they matter
Sea-level low points dominate the eastern seaboard and Gulf Coast because those states abut ocean basins and continental shelves; this has influenced coastal planning and flood risk policies since the early 20th century when tide gauges and topographic mapping became standardized.
Interior low points are commonly tied to fluvial erosion and drainage basins; rivers such as the Mississippi and Missouri serve as long-term geomorphic determinants of state low points and helped shape settlement patterns in the 18th and 19th centuries.
Practical uses of lowest-point data
Lowest-point elevations are used in engineering (levee and floodplain design), environmental planning (wetland and sea-level rise projections), and recreation (geotagging "lowpoint" visiting lists).
Emergency planners consult low-point databases when modelling storm surge and inland flooding; for example, federal and state agencies reference these benchmarks when updating coastal resilience plans on a cyclical basis-often tied to multi-decade historic storm records.
Quote and expert note
"Mapping low points is both a historical record and a planning necessity; these elevations anchor flood models and shoreline policy," said a senior USGS cartographer in a 2019 briefing on national elevation datasets.
How to read official low-point sources
Authoritative lists are usually compiled from USGS topographic data, state geological surveys, and vetted datasets like those used by World Population Review, World Atlas, and Statista; cross-referencing multiple sources is standard practice for journalists and planners verifying a state's low-point value.
Where to find full state-by-state data
Comprehensive tables listing every state's highest, lowest, and mean elevations are published by geographic data aggregators and often reproduced in roundups - examples include federal USGS publications and curated lists on reputable geography sites updated periodically (see World Population Review and World Atlas for recent compilations).
Quick reference - small printable checklist
- Check federal sources for the most authoritative elevation benchmarks (USGS).
- Use state surveys for local benchmark details and county-level coordinates.
- Consult updated compilations such as World Population Review and World Atlas for synthesized tables.
Helpful tips and tricks for Lowest Elevation Points In Us States Some Will Shock You
[How many states have their lowest point at sea level]?
Approximately 22 states and several territories have their lowest natural point at mean sea level along oceans or the Great Lakes shoreline, according to compilations of state low points.
[Which state has the lowest above-sea-level low point]?
Colorado has the highest "low point" among states (i.e., the lowest location within Colorado is ~3,315 ft above sea level), making it the state whose minimum elevation is the highest in the nation.
[Is any state entirely above sea level]?
No U.S. state is entirely above sea level in the sense of lacking any point at or below sea level; several are landlocked with all points well above sea level, but only coastal states have true sea-level low points and others have river valleys that define their minima.
[Can lowest points change over time]?
Yes. Human engineering (dredging, land reclamation, levee construction) and natural processes (subsidence, sea-level rise, erosion) can alter measured low-point elevations and local benchmarks; agencies periodically resurvey to keep records current.
[Can I visit every state's lowest point]?
Yes, many low points are publicly accessible (coastlines, riverbanks), though a few are on private land or in restricted areas; travel guides that compile "highpoint/lowpoint" tourism routes list access notes and recommended seasons.
[Where is the best single source to cite]?
For formal citation, the USGS and state geological surveys are preferred because they maintain original survey data and official benchmarks; aggregated lists are useful for quick reference but should be cross-checked.
