Research Methods
MEASUREMENT METHODS:
First, collect the measurement tools. To measure the depth of the lake, Lynn and Norma used a rope with weights, permanent marker, and a row boat.
Lynn and Norma: "We got into the boat that had a cord on the end. People helped us let some of the rope go and we drifted out to the middle of the lake. We dropped the weights over the edge of the boat. When we could feel that they hit the bottom, we marked the rope with permanent marker. We did this three different times in three different places and got three different results."
To record the water chemistry of the lake, Lynn and Norma had the help of a graduate student from the University of Washington who was working for the Yakama Nation in the natural resources division of the tribal government. He had a machine that could make quick calculations of the chemical content of water samples.
Although use of this machine was convenient, access to the data was not so easily obtained. Lynn and Norma had to wait for approval from tribal authority before using the data in their research because Olney Lake is on tribal land.
