Idaho Fishing Regulations Report: Guidelines and Rules for Anglers in the Gem State

Overview of Idaho Fishing Regulations and their Importance

Idaho Fishing Regulations

Fishing is one of the most popular outdoor recreational activities in Idaho, attracting thousands of anglers from all over the country every year. With over 2000 lakes and hundreds of rivers and streams, Idaho is home to some of the best fishing destinations in the United States.

However, fishing in Idaho is regulated by the Idaho Department of Fish and Game to ensure sustainable fishing practices that protect the state’s fish populations and aquatic ecosystems. The department sets rules and guidelines that anglers must follow when fishing in Idaho’s waters, including possession limits, size restrictions, and season dates, among other regulations.

Why Fishing Regulations are Important

Fishing Rules and Regulations

Fishing regulations are put in place to promote sustainable fishing and to protect fish populations and aquatic ecosystems. By following these regulations, anglers can help maintain healthy fish populations and preserve natural habitats for future generations.

Regulations on fish size and possession limits ensure that fish populations are not depleted, thereby protecting the ecological balance of the ecosystem. Fishing during the closed season is prohibited to allow fish populations to spawn and replenish, ensuring the continuation of the species.

Additionally, fishing regulations help prevent the spread of invasive species that can cause harm to native fish and aquatic habitats. Boats and gear used in other states or areas should be cleaned and disinfected to prevent the spread of invasive species that may threaten the local ecosystem.

Fishing in Idaho is a popular and enjoyable pastime, but it is crucial to remember that it is also important to fish responsibly. By following the Idaho fishing regulations, anglers can help ensure the sustainability of fish populations and preserve the aquatic ecosystems for future generations.

Fishing Licenses

Fishing is one of the most popular recreational activities in Idaho. With all the scenic bodies of water, both still and moving, it is no wonder why a lot of angling enthusiasts come to this state to fish. However, before you mindlessly cast a line, you must first make sure that you have an Idaho Fishing License.

A fishing license is a permit that authorizes anglers to fish in a specified location during a specific time. It is a requirement for all anglers above the age of 14, with some exceptions. An Idaho fishing license is issued by the Idaho Department of Fish and Game (IDFG), and it can be obtained through various means.

There are several types of fishing licenses, and each type is suited for different circumstances and anglers. Knowing which one to get can save you time, money, and avoid legal issues.

Resident Fishing Licenses

These types of fishing licenses are issued to people who reside in Idaho for at least six months or own a home within the state. There are different options for resident fishing licenses, and the fees vary depending on the type and duration of the license. For example, a one-year resident fishing license costs $25, while a three-year license costs $70.

Non-Resident Fishing Licenses

Non-resident fishing licenses are for people who do not reside in Idaho. The fees for non-residents are more expensive compared to resident licenses. The short-term non-resident fishing license is valid for one day and costs $13.75. On the other hand, a non-resident annual fishing license costs $98.25. It is worth noting that the fees for non-resident licenses are subject to change.

Combo Licenses

Combo licenses are for anglers who enjoy fishing and hunting. This license allows the holder to fish and hunt using a combination of tags, permits, and stamps. It is a convenient option for those who want to engage in both activities because they only need to carry a single license. The fees for a combination license vary depending on the duration and type of license.

Disabled Fishing License

The IDFG issues Idaho disabled fishing licenses for people with certain disabilities. These licenses are also issued at a reduced rate, and they are available for Idaho residents only. The fee for a disabled fishing license is $10, and it is valid for one year.

Youth Fishing Licenses

Youth fishing licenses are issued at a reduced rate for children under the age of 14. The cost of a youth fishing license is $13.75, which is the same as the short-term non-resident fishing license. The youth license is valid for one year, and it allows the holder to fish in all waters that require a fishing license.

In addition to the above types of fishing licenses, the IDFG also offers Military Licenses, which are for active-duty members of the military and their dependents. The IDFG also issues Pioneer Licenses to Idaho residents who are at least 70 years of age and have lived in Idaho for at least 30 years.

In conclusion, being aware of the different types of fishing licenses available in Idaho is crucial for anybody who plans to fish in the state. Having a fishing license not only allows you to fish legally but also supports conservation efforts to maintain Idaho’s aquatic resources.

Bag Limits

Idaho Fishing Regulations

When it comes to fishing regulations, Idaho has set bag limits for different fish species and waterways to ensure sustainability. As a fishing enthusiast, it is essential to know and observe these regulations to preserve the state’s fisheries for future generations.



Trout is one of the most popular fish among anglers and a vital part of Idaho’s fishery. The Idaho Department of Fish and Game has set bag limits for different trout species in different waterways to ensure their sustainability. In most rivers and streams, the limit for trout is six per day, with no more than one trout longer than 20 inches. In some waters, such as the Silver Creek, the daily limit is two trout per angler, and they must be released immediately. It is essential to check the specific regulations for the waterway you plan to fish on because the bag limits may change.



Bass is a game fish that can be found in different waterways across Idaho. The bag limit for bass is six per day, and they must be at least 12 inches long. However, in some waters, such as the Swan Falls Reservoir, there is a catch-and-release only requirement for bass until June 30th of each year. Moreover, in some waters, such as Hayden Lake, only one bass is allowed per day. Before going fishing, anglers should consult the Idaho fishing regulations to know the specific protocols for each waterway.



Panfish is a term that refers to different types of fish, such as bluegill, crappie, and perch. These fish species have a daily limit of 25 per day, with no minimum size restrictions. However, in some areas, such as the Deer Creek Reservoir, anglers are allowed to keep only ten panfish per day. To avoid any legal issues, anglers should check the regulations for the specific waterway they plan to fish in and follow them accordingly.

Salmon and Steelhead

Salmon and Steelhead

Salmon and steelhead are migratory fish species that require specific regulations to ensure their sustainability throughout their life cycle. Anglers are allowed to keep only specific salmon and steelhead species, such as Coho, Chinook, and Steelhead, and a salmon and steelhead permit is required. The daily limit for salmon and steelhead is six in total, but only three or four can be adults depending on the location and time of year. To minimize the impact on these fish species, some waterways may have specific regulations, such as a no-fishing period during spawning season. Anglers should familiarize themselves with the specific regulations for each waterway.


Understanding the regulations for bag limits is essential for any angler who plans to fish in Idaho. These limits are put in place to ensure the sustainability of the state’s fisheries. While they may vary by waterway and species, one must adhere to them to avoid legal issues and do their part in preserving the state’s fisheries. Before heading out for a fishing excursion, anglers should check the Idaho fishing regulations for updated information.

Many anglers indulge in fishing for the thrill of catching fish and then releasing them back into the water.

Idaho has several areas designated as “special fishing areas” that are managed differently than normal fishing zones. For example, the Silver Creek Preserve is a unique fishery that requires anglers to purchase a specific license to fish. Moreover, the rules governing fishing in the preserve, such as daily catch limits and harvest restrictions, differ from the state’s standard regulations. Other special fishing areas include the Teton River, where fishing is only allowed with artificial flies and lures, and the Kelly Creek, where anglers must use barbless hooks and release all cutthroat trout.

Seasonal Restrictions

Seasonal restrictions are an essential part of Idaho’s fishing regulations.

For instance, the state prohibits fishing for steelhead trout from April 1st to the end of July in most areas. Similarly, some water bodies have specific closed seasons for fishing; for example, Henry’s Lake is only open for fishing from Memorial Day weekend to November 30th.

Fisheries Management

The Idaho Department of Fish and Game (IDFG) is the primary agency responsible for enforcing fishing regulations in Idaho. They patrol the state’s rivers, lakes, and streams to ensure that anglers are following the rules. IDFG staff are authorized to ask anglers to show their fishing licenses and any fish they have caught. They may also use detection equipment, such as binoculars or boats, to watch for illegal activities.

In addition, other law enforcement agencies in Idaho, such as the Idaho State Police (ISP) and local police departments, may also enforce fishing regulations. The IDFG works closely with these agencies to ensure that fishing regulations are enforced and that violators are held accountable for their actions.


Jail Bars

Violating fishing regulations in Idaho can result in significant penalties. The severity of the penalties depends on the type of violation and the number of times an angler has broken the rules in the past. Penalties may include fines, loss of fishing privileges, and even jail time.

The fines for violating fishing regulations can range from $75 up to $10,000, depending on the type of violation and the number of times an angler has broken the rules. For example, fishing for bass during the closed season may result in a fine of $75 for the first offense. In contrast, fishing for salmon during the closed season may result in a fine of $10,000 and six months in jail.

Anglers who violate fishing regulations may also face the loss of their fishing privileges. For example, if an angler is caught using illegal fishing gear, their fishing license may be suspended or revoked. This loss of fishing privileges can last for several years.

Repeated violations of fishing regulations can result in more severe penalties. For example, if an angler is caught repeatedly using illegal gear, they may face more severe fines and longer revocation of their fishing privileges. In some cases, repeated violations may even result in jail time.
