Description:Aquatic Nuisance Species (ANS) are a significant and rapidly growing threat to Colorado’s water supply and to boating and fishing recreation. ANS are invasive animals, plants, and disease-causing pathogens that are “out of place” in Colorado’s rivers, lakes, streams, and wetlands. They are introduced accidentally or intentionally outside of their native range. Because they are not native to Colorado habitats, they have no natural competitors and predators. Without these checks and balances, the invaders are able to reproduce rapidly and out-compete native species for space and nutrients. ANS have harmful effects on natural resources, water supply systems and recreational opportunities. Once introduced, most invasive species cannot be eradicated and cost millions of dollars to manage. Preventing the introduction and spread of ANS is critical! [show more]

Fishing

Description:Live aquatic bait, such as minnows, crayfish, leeches, and mud puppies, can ruin fishing and introduce diseases to the fish already in the lake. Mussels and their microscopic larvae or plants can be transported in water held in the bait buckets or live wells. Once the boat is transported to another body of water, the Aquatic Nuisance Species (ANS) can be deposited into the new water. Anglers and boaters must take care not to move plants, animals, or water to a new lake or stream. [show more]

Fishing

Description:Keep all angling gear free of mud, plants, and organic debris in between each and every use. Unknowingly moving a species from one body of water to another, even within different stretches of the same river, can start a domino effect of invasion, causing irreversible ecological damage. It is especially important to keep waders clean [show more]

Fact sheet

Description:Colorado Parks and Wildlife coordinates a broad multijurisdictional watercraft inspection and decontamination network to protect waters from invasive zebra and quagga mussels and other invasive species. Recreational watercraft is the main vector of introduction for this harmful invader. Colorado is a headwater state and there are no mussels upstream. State certified inspectors repeatedly intercept watercraft infested with mussels. [show more]

Description:The State Aquatic Nuisance Species (ANS) Act was signed into law May 2008. The Act defines ANS as exotic or nonnative aquatic wildlife or any plant species that have been determined to pose a significant threat to the aquatic resources or water infrastructure of the state. The Parks Board passed regulations required by the Act on February 20, 2009 and updated them since that time. The regulations require mandatory watercraft inspection, and if necessary, decontamination of all boats coming from out of state, leaving waters with known ANS and boats entering high-risk waters where inspections are required by the managing entity. The focus of the program is to prevent zebra and quagga mussels and other ANS from infesting Colorado’s water resources and threatening our water storage and distribution systems for municipal, industrial and agricultural use. The Colorado ANS Program is highly effective and a model which other states across the nation are learning from. [show more]

Boating

Description:Some wakeboard boats, ski boats and sailboats have ballast tanks which are filled with water to stabilize the boat and allow them to ride lower in the water. Many ballast tanks can’t be visually checked, and many cannot be fully drained.

Description:The purpose of this compendium is to provide guidance to certified boat inspectors and decontaminators on various watercraft often used for recreational boating in Colorado. This book is not inclusive of all boats that inspectors may encounter, but provides detailed information for the majority of watercraft brands and different boat types. Included are the make and models along with the general anatomy of the watercraft, to ensure a successful inspection and/or decontamination to prevent the spread of harmful aquatic nuisance species (ANS).

Description:Preventing the introduction and spread of Aquatic Nuisance Species (ANS) is critical to protect water resources! ANS are a significant and rapidly growing threat to Colorado’s water supply and to boating and fishing recreation. ANS are invasive animals, plants, and disease-causing pathogens that are “out of place” in Colorado’s reservoirs, lakes, rivers, streams, and wetlands. They are introduced accidentally or intentionally outside of their native range. Because they are not native to Colorado habitats, they have no natural competitors and predators. Without these checks and balances, the invaders are able to reproduce rapidly and out-compete native species. Once introduced, most invasive species cannot be eradicated and cost billions of dollars to manage. [show more]

Description:The purpose of this workbook is to provide consistent guidance to State of Colorado Aquatic Nuisance Species (ANS) Trainers who are responsible for certification of individuals as Authorized Agents for the purpose of ANS Watercraft Inspection and Decontamination. It is of the highest importance that Authorized Locations (a.k.a. Watercraft Inspection and Decontamination Stations or WIDS) within Colorado are implemented and operated in a consistent fashion. The foundation of the WIDS network begins at certification training. Regardless of jurisdiction, Colorado Authorized Locations, Agents, and Operations should appear seamless to the boater because they are implemented with consistent messaging, education, inspection and decontamination procedures as taught in this course.
