RE: Division of Water Resources Satelli linked Monitoring System
DWR and CWCB Flood Hardening of Existing Stream Gages
The Colorado Division of Water Resources requests $350,000 from the CWCB Construction fund far FY09.
The funds are for continued, long-term operational viability of over 450 satellite-linked water monitoring
sites, renovation of existing gaging stations, and replacement of out-dated data collection platforms and
upgrading of transmission components. 1n addition, many existing gaging stations need to be modified #o
provide critical stream flow tlata for flood warning and high flow monitoring. The specific distribution of the
funds requested is as follows:
1. $245,000 for replacement of out-dated Data Collection Platforms (DCP) and associated satellite
telemetry equipment and upgrading of satellite transmission components. This request is for the
ongoing program to upgrade data collection platforms with high data rate satellite telemetry.,
2. $55,000 for refurbishing existing stream gages as needed to maintain operational reliability of
stream flow data. This request is anticipated to be an annual cost due to deterioration and
projected life expectancy of the physical and mechanical aspects of the stream gages.
3. $50,000, jointly requested by OWR and CWCB, #or flood hardening and high flow measurement
sustainability at stream gages around Colorado.
Introduction
The Division of Water Resources and CWCB, consistent with Section 37-60-121 and Section 37-80-102
C.R.S., continue to improvethe utility of the stream gaging program to support multi-agency and water
user needs such as flood forecasting and warning, water rights administration, compact protection, and
Decision Support System implementation and use. DWR must maintain the electronics in satellite-linked
data collection stations, refurbish the station structure and non-electronic hardware for stations that are
deteriorating, harden certain key stations against flood events so that we can continue to collect critical,
real-time stream flow data iri times of flood, refurbish and replace cableways used for high flow
measurements and subsequent calibration of the upper end of stage-discharge relationships, and
continue, as necessary, the operation of vital gages which are currently operated by the United States
Geological Survey (USGS). This is part of a continuing annual request for funds to support this program.
