Chapter III . Background Information

Historically, there has not been augmentation of evaporation or out-of-priority storage of

water in Monument Lake. In the event such augmentation is required in the future, the Town is

prepared to do so as follows:

On September 21, 1998, the Town entered into an agreement "for the purchase of water"

with Colorado Springs Utilities (CSU). Under t/lis agreement, sufficient water is available to the

Town at a reasonable price to augment that evaporation and to fill Monument Lake. The

agreement will completely cover all requirementS of Colorado Springs so long as Monument

Lake is only used for recreation purposes. In the event the Town may elect in the future to use

the lake for purposes other than recreation, an effort would first be made to broaden the uses

allowed under this agreement. Failing that, the Town has sufficient senior water rights on Beaver

Creek, or return flow credits from use of its non"tributary Denver based and aquifer water, to

augment all out-of-priority depletions. A copy of the agreement is presented in Appendix C.

The agreement with CSU is premised on the fact that Colorado Springs owns the pivotal

call on Monument Creek. There are, however, other junior water rights, which also exist on the

stream. To the extent there is any legal requirement to augment depletions experienced by other

water rights, the above-mentioned senior rights on Beaver Creek and non-tributary return flow

credits suffice for any lawfully required augmentation.

F. Field Investigations

The section contains a description of the subsurface investigation program, subsurface

conditions, and a summary of the laboratory test data. The information obtained from this field

program and from the available information furnished to Boyle by the County, Town and SEa

formed the basis of the geotechnical evaluations and feasibility design.

Three borings, numbered BIOi, B102, and BI03, were performed on March 16 and 17,
1999. Linmon Environmental Drilling Company, from Colorado Springs, Colorado, drilled the
borings. Two of the borings (B 10 1 and B 1 02) were drilled from the crest of the dam, and B 103
was drilled at the downstream toe of the dam. After the borings were completed, the boring
locations were surveyed. A plan of the boring locations is shown on Figure III-3.
