• Description: CWCB Director's Report
• Board Meetings - Doc Type: Memo

Flood Season 2005: The kick off meeting for the Colorado Flood Task force is scheduled for April 6,
please visit the CWCB website for details and the agenda. The watershed and counties south of the 1-70
corridor tends to be much above of average and will be under review for spring snow melt flood threat.
The staff in cooperation with SNODAS are working as a new forecast model. It is expected to be
experimental for 2005 flood outlook season.

Flood Program Conferences:

. Tom Browning and Kevin Houck are in Montana for a FEMA Region VIII flood conference. Mr.
Browning was asked to give a presentation on the RlCD experiences and opportunities as they
relate to floodplain and stream restoration programs.

c Every year the CWCB sends to Flood Staff members to the Association of State Floodplain
Managers Conference. The ASFPM Conference is in Madison WI, is on ASFPM 2005 Annual
Conference June 11 - 17, 2005 Madison, Wisconsin. hrt1J://www.floods.org/bome/default.asp

. Weather Modification Association Annual Conference 2005 Annual Meeting is being held April
27-29 in Rockville, Maryland. The CWCB has attended this conference since 2003 and is member
of the North American Interstate Weather Modification Council that is comprised of westem states
government operators and regulators of weather modification programs (visit
htto://www.weathermodification.org/); This year the WMA is hosting a legislative reception to
inform Congressional delegations about the importance of weather modification operational
programs and scientific evaluations in western states.

Weather Modification Updates:.

. Wyoming approves nearly $9 million for WM: Wyoming Governor Dave Freudenthal signed into
law House Bill 141 Onmibus Water Planning which contains nearly $9 million dollars for weather
modification operations and research in the State of Wyoming in late February 2005. The large
amount of funding enables Wyoming to develop a state ofthe art seeding program with state of
the art evaluation. CWCB Staffwill monitor and report to the board on this initiative as some of
these evaluations will have directly applicability to Colorado and its Weather Modification
operational programs. For more information about their program contact Barry Lawrence, WM
Project Manager, Wyoming Water Development Commission at: 307 777 7626 or email him at

. Hail Suppression Standard Available ASCE-EWRl Standard 39-03, Standard Practice for the
Design and Operation of Hail Suppression Programs, is now available from ASCE publications at
hrt1J:/ /www.asce.org/publicationslbooksdisplav.cfrn?tvoe=9991621.This standard, developed
through ASCE's consensus process, was the basis for a workshop jointly sponsored by the WMA
and ASCE's Environmental and Water Resources Institute in April of2003.

. Guidelines for Cloud Seeding to Augment Precipitation (ASCE Manual No. 81), is the outgrowth
of a corrnnittee report by the same title published by the ASCE Weather Modification Committee
in the March 1983 issue of Journal of Irrigation and Drainage Engineering. A task committee of
the ASCE Climate and Weather Change Committee has expanded and updated this report to
provide water resources managers and others who might become involved in the decision-making
process for implementing a cloud seeding proj ect with the necessary guidelines. The sections of
this manual cover essentials of weather modification including the social, legal, environmental,
and economic aspects as well as the scientific basis. Further, the manager is guided through the
professional practice for operational cloud seeding, from materials and devices necessary to
produce ice crystal-forming nuclei to the methods for distributing the artificially produced nuclei
