Several species of fish were acoustic and radio tagged downstream of Lock and Dam 2 [Fish LD2.txt].
their detections are listed in data LD2.txt. These are filtered detection: false positive were removed [unfiltered data can be obtained by contacting js.finger@yahoo.fr].

Receivers ID are associated with Locations using receivers.txt
Locations are shown in map found in the repository [map LD2].

Some of these fish were actively tracked below the spillway gates of Lock and Dam 2.
Their position can be found in Track LD2.txt

Processed active tracking data giving fish positions and depths [raw data can be obtained by contacting js.finger@yahoo.fr].

Fish position is obtained using biangulation analyses.
Depth data has been converted in meters using X(PSI)*2.306658*0.3048+0.7
0.7 (m) is slightly less than 1 PSI. This is used to give the upper interval limit:
if a fish is detected at 0 PSI then it is between 0 and 0.7 meters.
