Use the map below to learn more about the six HRBMP surveys. Click on the different regions of the Hudson River to see what surveys occurred there and when the regions were surveyed.

In order for the HRBMP to capture fish at all life stages, a series of distinct surveys using different gear types were developed. The major surveys covered the length of the river from the Troy Dam in Albany to New York City. The map above shows the extent of the different surveys. Click on the colored sections of the river for additional information. For more detailed descriptions about the six surveys, click on each of the pages under The Survey tab.
