The hydrogeology of this project is used to predict some of the figures that are used with the other team members' components. Determining these values can be used to create a logical answer for this project.

The values that were of most importance in this project were of volume and drainage longevity of the lake's water content. Consumption rates for the State of California are of extreme interest to the project in order to determine an appropriate time period to drain the lake. In order to understand the hydrogeology of Crater Lake, the investigation of groundwater movement and flow of the lake's water was a key factor.

The public claims that springs are resurfacing from the lake's water content. With the information that is available, the investigation of outflows and inflows of hydrothermal variability is explained to establish a better truth than that created by the public and community. Methodology Volume of Crater Lake.

The volume of Crater Lake was determined by assuming that the lake was a frustum of a cone see attached diagram. The formula for the volume of a frustum of a cone is: The complexity of finding volume of Crater Lake's frustum shape consisted of locating information available stating different dimensions of the lake.

Two radiuses were to be determined; one radius of the surface water R and one radius of the lake's bottom r. The dimensions of the surface water were found to be 6. There were no clear dimensions of the current floor of the lake, but at the time of the creation of the caldera the width of the base was approximately 5.

The depth of the lake is 1, feet National Park Servicewhich is the "h" in the equation.

The radius is equal to half the length of the diameter. To generate an estimated model of the frustum of the cone the average of the two diameters of the surface water had to be found.

This was done by adding 6. This value is 5. The radius value for the surface water R of the frustum model is then 2. The bottom of the lake's diameter is 5. R then equals 2.


However, these quantities must be converted to feet. The conversion of miles to feet is that there are 5, feet per mile Chicago Turnite. With these values the volume of Crater Lake can be found.

So again, the formula for volume of a frustum of a cone is: With this formula the quantities from above can be plugged in: This number needed to be converted to gallons. Given from that 7. The volume of Crater Lake is 8,, gallons.

Detailed components of equations on spreadsheet. Research was done in order to determine the State of California's consumption rate. The California Energy Commission provided the figures for this annual rate. After determining that the State of California consumes One acre foot is equal togallons Chicago Turnite.

This value is the amount of gallons being consumed per year by the State of California. So the amount of time it will take to drain Crater Lake is determined by volume of the lake divided by the amount of water California consumes per month: It will take only a little over five months to drain the lake.

There have been many assumptions and unsubstantiated rumors of springs to resurface near the Klamath River due to Crater Lake. These reports of hydrothermal outputs by Crater Lake are very difficult to provide substantial evidence that they are true.

However, there are many reports on the activity of the thermal inputs to Crater Lake that cause temperature variability. There are several hypotheses for the thermal fluctuations in the near-bottom waters of the lake.

Some of these hypotheses include the "convection of waters through cooling magmatic bodies that underlie Crater Lake" Collier and Dymond, Other hypotheses suggest that "a landslide may provide a more permeable pathway for heated water from ring-fracture sites reach the lake-floor surface" Bacon et.Essay for crater lake.

Crater Lake: Hydrogeology The purpose of this memorandum is to provide a summary of the hydrogeology of Crater Lake located in Crater Lake, Oregon in support of the project questioning whether to sell Crater Lake's water to California providing a landfill for waste or keeping the lake for its recreational value.
