LMVP Data

The Map of LMVP Sample Sites allows access to individual lake data and can show you a satellite image of the lake. Please be patient, as the map may take a moment to load.

The map can be manipulated in 3 ways. You can zoom in, change the view from street map to satellite, and you can move the map around. Give it a try!

Some lakes have multi-year Trend Analyses available. All data used for these Trend Analyses are normalized to display "summer" values only. So, data collected before May 15 and after September 15 are not included in the multi-year graphs. This helps reduce inequities introduced by an early sampling season in one year versus a late start in another. In effect, it allows us to confidently compare (within a lake) the data of one year to the data of another.
These data are often depicted using box plots. Box Plot help.

We frequently use "Julian Day" in our analyses. Each day, starting with January 1, gets its own "Julian Day". So January 1 is Julian Day number one. February 1 is Julian Day number 32. Data are corrected for leap years. Here is a handy Julian Day Calendar.

LMVP data are presented in the Adobe Acrobat PDF format. This is a common method for distributing documents on the web. Many of the Missouri DNR and US Corps of Engineers documents available here are also in the PDF format.
