This project entails the continued implementation of a statewide engineering , technical , and
support services program to help address consulting engineering and other professional service
needs of the Colorado Water Conservation Board Instream F low and Natural Lake Level
Program.

The fund will be used to retain consultants to perform eng ineering support services for the
and for providing (1) technical and

scientific bases for new appropriations, and (2) technical analys e s for the transfer of acquired
water rights to instream flow use , all on an as - needed basis. In addition, the fund will be used to
retain other personal services contract or temporary employees to provide technical and/or data
maintenance assistance to ISF program staff.

The CWCB relies upon sound technical investigations to appropriate, acquire, and protect
instream flow water rights throughout the state. Due to a steady increase in water court matters ,
flow water rights continues to grow. For example, resume review activities , including injury
analyses that provide justification for filing of Statements of Opposition , requires significant
staff resources. In addition, technical investigations are needed to proce ss the acquisition of
senior water rights and to provide technical support and expertise to change the decreed uses of
the acquired water to instream flow use.

Likewise, engineering support services may be needed to conduct water availability analys e s for
streams on which the Board is considering appropriating new instream flow water rights. This
appropriation by analyzing available gage records, diversion record s a nd call records, using
available stream flow models, and developing stream flow models or utilizing appropriate
standard methods to develop hydrographs to predict the natural (virgin) streamflows for each
stream under consideration.
