A Survey Is a Baseline Before It Is a Verdict: What Missouri River Towns Should Record Now

A wildlife survey on the Lewis and Clark route shows why any town drawing water from a river needs a dated record of what is there before it can tell what has changed.

On November 14, 2026, The Guardian published a report on Indigenous students who are retracing the route of the Lewis and Clark expedition. According to the summary of that Guardian report by Ashley Stimpson, the students are conducting a new wildlife survey along the route about two centuries after the expedition. In 1804, Thomas Jefferson sent Meriwether Lewis and William Clark and the Corps of Discovery into the land west of the Mississippi, and the summary notes that the president's main aim was political. The survey has a different purpose. It asks what lives on the land today.

The headline carries the lesson in a single line: "We can’t protect what we cannot see." That sentence applies well beyond wildlife. A town that draws its drinking water from a river, a reservoir, or an aquifer depends on a source that changes over time, and the only way to notice a change is to have a record of how things looked before it happened.

What a Survey Captures

A wildlife survey is a snapshot. Field crews record which species are present, where they are found, and what the habitat looks like at the time of the visit. A good survey also records the method, the date, and the location, so that a later crew can return to the same places and compare notes. The value comes from repetition and from the paperwork that makes repetition possible.

Water systems work the same way. An intake on a river, a well field, or a reservoir shoreline has its own conditions, and those conditions shift with rainfall, upstream land use, and seasonal flows. A utility that knows only the current reading cannot say whether the reading is unusual. It needs an earlier reading, taken the same way, to compare against.

Baseline Is Not the Same as a Verdict

A baseline is a starting point, not a conclusion. It tells you what was normal when someone measured it. It does not tell you that the source is safe or unsafe, and it does not replace the professional testing that water utilities and state agencies carry out under their own rules. Residents sometimes hear the word "baseline" and assume it means a clean bill of health. It means only that a record exists.

Three kinds of records often get confused. A source water description explains where the water comes from and what surrounds it. A monitoring program repeats measurements on a schedule. A one-time study answers a specific question at a specific moment. Each has a different use, and a town that has only one of them should know which questions the others could answer.

Questions to Bring to Your Utility

A town board meeting or a utility's public office hours are good places to ask for the records. These questions do not require technical training, and they tend to get clearer answers when they are specific:

Where does our raw water come from, and is there a written description of the source?
Who collects source water samples, how often, and where are the results filed?
Is there a dated record from before any recent change to the intake, the pumping schedule, or the land upstream?
If the staff member who keeps these records leaves, who takes over the file?
Can residents request copies, and how long does that usually take?

If the answer to any of these is "we will look into it," that is a useful answer too. It tells you where the record gap is.

Keep the Record Where People Can Find It

A baseline is only useful if someone can find it years later. Copies of key records can be kept with the town clerk, the utility office, and a local library or historical society. Each record should carry a date, the name of the person or agency that made it, and a short note about the method. Filenames that include the year and the site make a folder easier to search when the next question arrives.

The Lewis and Clark survey is a reminder that a route can be retraced only if someone wrote down the first trip. Midwest towns that depend on rivers and aquifers are in the same position. The record that matters most is often the one nobody thought to make until the water changed.
