• Description: CF Section - Severance Tax Trust Fund Operational Account Recommendations
• Board Meetings - Doc Type: Memo

Water Planning Relationship: Sago pondweed (Potamogeton pectinatus L.) and Eurasian
watermilfoil (~l7yriophyllum spicatum L.) infestations reduce the efficacy of water delivery and the
quality of water storage and recreational reservoirs. Sago pondweed is a native submersed aquatic
plant that causes recurring problems in irrigation canals, while Eurasian watermilfoil (EWM) is a
non-native, aquatic species that is becoming more common across Colorado. Currently available
control options for these two aquatic species are very costly and in the case of Magnacide®
(acrolein) can be very hazardous to the applicator.
While sago pondweed has been a problem for irrigation districts for many years, EWM is an
emerging threat that could have more significant impacts. EWM is considered the hydrilla of
temperate climates. It is a very serious submersed aquatic weed species infesting many areas of the
USA. EWM interferes with recreational activities (boating and swimming), power generation, and
sport fishing. In Colorado, EWM is moving from Boulder Creek into irrigation systems supplied by
Boulder Creek. The State of Idaho provided 4 million dollars to assist various state and local
agencies with efforts to map and manage EWM infestations, as well as increase public awareness of
how this invasive weed species can be spread by boating and fishing activities. That is a good
indication of how serious this problem could be. In contrast to Idaho's situation, Colorado is in a
much earlier stage of the invasion process and many of the sites currently infested have limited
access. This provides Colorado with an opportunity to mount an effort of containment, management
and education.
Recommendation: Staff gives a low recommendation for funding of this project because other
funding may become available through the Projects Bill.
6. Instream Flow Decision Support System Technology Enhancement
Beneficiary/Grantee/Contractor: CWCB, Various
Amount of Request: $25,000 Ranking: Medium
Product Produced: An enhanced Instream Flow Decision Support System (ISFDSS). Since the
Stream and Lake Protection Section began using an ISFDSS, several enhancements were identified
that would increase the versatility of the DSS as well as updating the system to account for new
technology updates.
Water Planning Relationship: The ISFDSS continues to help meet the objective and goals
listed in strategic plans for both Water Information and the Stream and Lake Protection Sections.
Recommendation: Staff gives a medium recommendation for funding of this project because
other funding may become available.
Intra-State Water Management Program
1. Water Supply Reserve Account Follow-Up
Beneficiary/Grantee/Conh•actor: CWCB, Various
Amount of Request: $500,000 Ranking: Medium
Product Produced: These funds will allow the CWCB to help Water Supply Reserve Account
(WSRA) grant recipients to realize the full potential of their projects by providing additional
technical support. More than 50 WSRA grants have been reviewed and approved by the Board.
Many of these grants are for specific planning activities that will take additional funding and
