This page contains descriptions of sampling sites. The Site Number is the designation as found in the database. Beginning with the 1998 data, site numbers end with an S (shallow), M (middle), or D (deep) to indicate sampling depth. The depth in meters can be retrieved too. The Alternate Designation column lists other site codes that correspond to the same location.

The sites are listed by survey group and correspond to maps available from the MMSD Historical Data main page. An alphabetic list of site numbers is also provided.

Notes

River Mile 0.0 is confluence of the Menomonee River with Milwaukee River.

1 Sampling at Sites NS-6 and NS-9 ceased in 1993 after data comparison revealed no statistical difference between NS-5 and NS-10 respectively. These locations will serve as historical references only.

2 This site is no longer sampled due to land access restrictions. Last year of sampling was 1988.

3 Field Site number changed in 1998 from "RI" to "OC", historical data prior to 1998 uses the "RI" designation.
