<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This layer represents river and lake bank condition surveys over multiple years. Bank geometry is updated with each survey based on the latest imagery available at the time of the survey. Bank surveys are conducted in the waterbody by collecting a GPS point where bank condition or structure changes. The attributes of the GPS point are then applied to the downstream portion of the bank, until a new change occurs. GPS point attributes are applied to the updated bank lines via a Python script or manual editing process in the office.</SPAN></P><P><SPAN>Ecosystem Diagnosis and Treatment (EDT) reach attributes are recorded for the surveyed streams.
