STATEMENT OF WORK

HYDROLOGIC DATA COLLECTION

BACKGROUND

Work consists of tasks listed below for sites located within the Bureau of Reclamation’s Upper Colorado region. The work is to be performed within the state of Colorado, on the San Luis Valley Project, Closed Basin Division. The Closed Basin Division is in south central Colorado in the San Luis Valley in a topographic basin called the Closed Basin. The Closed Basin has a surface area of 2,940 square miles.

The contractor collects hydrologic data from the waterways, pumping plants, and measuring structures within the Closed Basin Division Project area. This data provides the proper accounting of Project waters in compliance with the Rio Grande Compact and a mechanism for the Project personnel to verify the accuracies of the water measuring devices currently being used within the Project.

Accurate reading and analysis of readings are critical to downstream reporting and is presented at the Compact Commission Meeting. Data is reviewed by the Colorado State Engineer and the Rio Grande Compact Engineer Advisor and must meet USGS Standards or greater.

SCOPE

• The gauging and rating program will continue to be followed under this contract as deemed reasonably necessary with respect to circumstances and duties to be performed.

Gauging is performed at Parshall Flume twice a month and a measurement note shall be produced for each measurement

• Contractor personnel will be available to provide Bureau personnel with data and advice regarding water measuring devices located on the Closed Basin Project.

• Monthly discharge records for the Parshall Flume and periodic shift information will be provided to Reclamation within five working days of the end of each month.

• The original data will be filed electronically by the contractor for the period required by the Rio Grande Compact for hydrologic data. These records will be available to Reclamation, the Compact Commission, and other agencies for publication or other related work.

OBJECTIVES

The objective of this contract is to acquire contractor services to collect hydrologic data from the waterways, pumping plants, and measuring structures within the Closed Basin Division Project area.

TASKS

Data Collection Activities: Data will consist of copies of all field measurement records for all sites; developed rating tables for water measuring structures and other devices. Stream gauging to collect surface water data from the Parshall Flume at Sta. 281 + 00 will be performed twice monthly. Contractor personnel will measure the flow through additional water measuring structures and devices at specific locations on an as needed basis, not to exceed three visits per site per year. Other sites are as follows:

Site Normal.

Freq.

CHO1, CHO2, CHO3, CHO4 – all have flow meters various

Alamosa National Wildlife Refuge Pumping Plant – Gauging Station various

San Luis Lake Pumping Plant Discharge – flow meter various

San Luis Lake Feeder Canal - flow meter various

San Luis Lake Flume – flow meter various

San Luis Creek at San Luis Lake – Gauging Station various

Head Lake Turnout – no equipment seldom

Head Lake Flume – no equipment seldom

Big springs Creek Flume – Gauging Station various

Rate Devices: Perform the rating of the Stevens Recorder located at the Parshall Flume at Sta.

281 + 00 defined by Reclamation on a semimonthly basis.

•This data will be utilized by Reclamation to verify the accuracies of the water measuring devices, to monitor surface water conditions, and to account for water salvaged and delivered from the Project.

CONTRACTOR PERSONNEL

The following activities shall be supervised by key personnel:

The gauging and rating program will continue to be followed under this contract as deemed reasonably necessary with respect to circumstances and duties to be performed.

Gauging is performed at Parshall Flume twice a month and a measurement note shall be produced for each measurement

Contractor will provide a shaft encoder and data collection platform system as well as a backup recorder system at the gauging station located adjacent to the 12-foot Parshall Flume. Contractor personnel shall operate and maintain these data recorder systems.

(The equipment belongs to the contractor and cost for its use is included in cost for the service)

When necessary, the chart recorders, shaft encoders, and data collection platforms installed at the 12-foot Parshall Flume gauging station will be repaired or replaced by contractor to ensure data reliability.

Contractor personnel will be available to provide Bureau personnel with data and advice regarding water measuring devices located on the Closed Basin Project.

The data collected is analyzed and the results forwarded within five working days after the end of the month in which the work is performed.

The data consists of copies of all field measurement records for all sites and developed rating tables for water measuring structures and devices.

Monthly discharge records for the Parshall Flume, and periodic shift information will be provided to Reclamation within five (5) working days of the end of each month.

The original data will be filed electronically for the period required by the Rio Grande Compact for hydrologic data. These records will be available to Reclamation, the Compact Commission, and other agencies for publication or other related work.

Key Personnel:

Personnel will coordinate work schedules and changes with Contracting Officer’s Technical Representative twenty-four hours in advance.

Field Equipment Requirements:

All necessary equipment and supplies shall be provided by the Contractor. No additional payment will be made by the Government for the use of other incidental equipment required for the performance of the work.

DELIVERY

REPORTING

Data will consist of copies of all field measurement records for all sites; meter readings, developed rating tables for water measuring structures and other devices; monthly and annual record production conducted by hydrographic technicians, and hydrographic engineers based in the Alamosa CDWR office; reviews conducted by Chief Hydrographic Engineer in Denver and/or the USGS. Costs shall include travel costs. Maintenance of equipment used in performance of this contract will be the responsibility of the contractor. Reports will be submitted to Reclamation monthly within five (5) working days after the end of each month.

The data collected under this contract shall be analyzed and the results forwarded as outlined above to the following Reclamation offices:

SAFETY

Field work shall be performed in accordance with Reclamation's publication "Reclamation Safety and Health Standards" (RSHS). The Government has provided the contractor with a copy of this publication.

PLACE OF PERFORMANCE

Contractor will perform and collect surface water data from the Parshall Flume at Sta. 281 + 00 twice monthly.
