Mr. Brandon Stidham Johnson Bros Corporation KY Dam Lock Addition 192 Taylor Park Rd Grand Rivers, KY 42045

Mr. Stidham, Under cover of this letter, we are providing the following:

• 2017 System Maintenance and Troubleshooting Report

• Summary of System Component Replacement since June, 2010

• Listing of On-site Instrumentation Materials

• 2017 Cumulative data plots for:

o Tilt Meters o Joint Meters o VW Piezometers o In-place Inclinometers (60 day increments)

It should be noted this is a 2017 Annual Maintenance Report and is not intended to discuss data in detail.

This is accomplished in the monthly reports.

The new Campbell logger is now called logger 204.

August 12, 2017—Replaced the internal and external batteries in Logger 101,106 and 201 August 12, 2017—Replaced the internal battery in Logger 109 August 14, 2017—Replaced the vibrating wire board on logger 103.

August 29, 2017—Replaced the internal battery on logger 202.

October 18, 2017—Replaced the external marine battery on logger 202 & 204.

October 19, 2017—After troubleshooting IPI 7-1Y it has been determined that the sensor is damaged, the core has decided to turn off the alarms on the sensor.

November 13, 2017—Replaced the external marine battery on logger 202 & 204.

December 13, 2017—After troubleshooting IPI 2-2 and 4-4 it has been determined that the sensors are damaged, the core has decided to turn off the alarms on the sensors.

December 14, 2017—Replaced Logger 200

Tiltmeter:

All readings appear to be within expected range with the exception of the following sensors that were decommissioned.

• TM-04 in August of 2017.

RBMD:

RBMD’s 9/10, 10/11, 11/12, 12/13, and 13/14 are up to date and within expected range.

RBMD’s 1, 2, 3, 3/4, 4, 4/5, 5/6, 6/7, 7/8, and 8/9 were decommissioned in March of 2017.

Alignment Pin:

All readings appear to be within expected range.

Joint Meters:

All readings appear to be within expected range.

VWPZ:

Piezometers 11, 12, 13, 14, 15, 22, 23, and 24 were offline November 5th to December 15th of 2017 due to troubleshooting and VW board replacement of logger 200.

In-Place Inclinometers:

All readings appear to be within expected range with the exception of the following exception:

• IPI 2-2 and IPI 4-4 were decommissioned in December of 2017.

• Due to invalid data up to 4/11/2017 and a 60 day graphing interval the graph for IPI 7a-X starts on

5/5/2017. Invalid data until 1/18/2017 causes the graph for IPI 7a-Y to start at 3/6/2017. The outlying data points for IPI 7a-X and 7a-Y on 7/4/2017 are caused by invalid data during that time.
