Water Depth sensing system

Overview
The level of the Lake varies after rain storms. It would be nice to know how much, and to be able to review this information remotely. A Raspberry Pi and a depth sensor should allow this to work given a fixed sensor at a "Known" depth. The idea being to determine how much water is above the sensor at any given time.
The Raspberry Pi doesn't have an on-board ADC so an additional circuit is required to register voltage increases from sensors.

Possible Alternate Sensor Technology
- Optomax Digital Liquid Level Sensor - It's a Binary On/Off switch, but could be used to detect the simple presence of water at a given level in or below a building. IE: Has water reached the joists? Is water inside the cabin?
