Wild and Scenic Rivers Fund

In 2009, the Colorado General Assembly created the Wild and Scenic Rivers Fund to foster cooperative and collaborative processes aimed at the development of protections for river-dependent outstandingly remarkable values (“ORVs”). These protections would be intended as an alternative to wild and scenic river designation under the federal Wild and Scenic Rivers Act, while also protecting Colorado’s ability to fully use its compact and decree entitlements.

The Colorado General Assembly established the Colorado Water Conservation Board’s (CWCB’s) Wild and Scenic Rivers Fund (“the Fund”) in 20091. The legislature:

• Provided that the Fund would be refreshed annually up to $400,000;
• Stated that the Fund should be used to “work with stakeholders within the state of Colorado to develop protection of riverdependent resources as an alternative to wild and scenic river designation under the federal Wild and Scenic Rivers Act”; and,
• Provided that the Board may adopt terms and conditions here called “guidelines” for fund disbursements.

The Fund is used for two primary purposes: 

• To support local resource protection groups (“stakeholder groups”) that form to develop protection of river-dependent resources as an alternative to wild and scenic river designation under the federal Wild and Scenic Rivers Act, exploring different approaches that will most benefit the resource and the community, and 
• For CWCB Staff operational expenses related to participation in such stakeholder groups.

These guidelines are designed to assure that the Fund is used to support the efforts of these various stakeholder groups in an equitable and efficient manner. It is the goal of the CWCB to ensure wise and effective use of monies from the Fund. The CWCB strongly encourages the use of this Fund for projects that result in the compilation of the best available data at the earliest stages of the federal agencies’ plan revisions and processes to evaluate streams and rivers for eligibility and suitability for Wild and Scenic designation. Colorado's Instream Flow Program offers a means to protect flow-related Outstandingly Remarkable Values (ORVs) without a Wild and Scenic designation; thus, stakeholder groups are encouraged to consider instream flows as a primary tool in the effort to protect such ORVs

Technical Assistance for Federal Cost-Sharing Program

The Technical Assistance for Federal Cost-Sharing Program (TAFC) helps Colorado water users secure and use federal money for water projects. The TAFC Program's main purpose is to provide technical and administrative support to organizations applying for federal funding. This program is especially helpful for water users who struggle to access federal funds due to limited staff or technical resources.

The TAFC Program offers grants directly to water users. These grants can be used to hire consultants or get other necessary resources to create strong applications for federal funding. All projects funded by TAFC must align with the Colorado Water Plan and can include projects involving aging infrastructure. TAFC grants cannot be used for treated water projects or wastewater projects.

The CWCB has $500,000 available for projects across Colorado. Applications will be accepted on a rolling basis.

Grant funding can be used for tasks such as:

• Preliminary project planning, design, and engineering
• Preliminary permitting
• Developing estimated project costs
• Understanding available federal funding opportunities
• Grant writing
• Submitting federal grant applications

Project development: This includes site assessments, data collection for project design, working with other interested parties, permitting, design help, cost estimates, securing matching funds, and other technical work needed for a federal funding application.

Grant writing: This covers researching federal grant opportunities, contacting funding programs before applying, reviewing federal rules and application requirements, and creating the application and required documents like support letters.

Aquatic Invasive Species Control – Large or Small-Scale Population Management

(See page 31 of attatched PDF)

When an established population of aquatic invasive species is having adverse effects on a waterbody or wetland, funding is available for control activities. Managing aquatic invasive species can be challenging, but adaptive and integrated pest management can help. Participation in the large- or small-scale control program requires an approved recommendation in an aquatic plant or aquatic invasive species management plan. Eligible projects will implement one or more of the resulting recommendations. Public access required, unless controlling a prohibited species.

DNR cost share: Grants may cover up to 75% of total project costs.

The AIS Population Management Grant includes Small-Scale Population Management Projects and Large-Scale Population Management Projects.

Small-Scale Population Management Projects

Small-Scale Population Management projects will maintain a low abundance of one or more aquatic invasive species populations or further reduce their size. Projects should implement management activities with the goal of continued suppression of the target species where the actions are unlikely to affect the entire lake, stream reach or wetland. Projects should be designed to result in long-term, multi-season suppression of one or more established populations of the target species.

Large-Scale Population Management Projects

Large-Scale Population Management projects will result in long-term, multi-season suppression of one or more established populations of aquatic invasive species. Projects are large in scale, affecting a substantial portion of a lake, stream reach, or wetland.

Projects that address multiple populations across a region should employ a strategic approach to managing multiple populations, prioritizing control actions in a way that ensures wise spending of grant funds. For example, a regional wetland control project might focus on populations that threaten high-functioning natural wetlands or focus on small, more easily controlled populations. For Phragmites-focused projects seeking AIS planning and control grant funds, please see the Phragmites Statewide Management Strategy for more specific guidance.
