Federal reservoirs: Army Corps, BOR, and TVA

Orientation only. Verify current rules with the project office before launching. See Waterway Rules hub for jurisdiction overview.

• The Army Corps of Engineers manages over 400 lakes and reservoirs in the United States. Most were built for flood control, navigation improvement, or water supply, and recreation access is a secondary use. Corps lakes are among the most heavily used recreational waters in the country (they're not private), but access and operational rules are set by the Corps, not the state, for activities within Corps-managed land and water.
• Each Corps project has its own rules. There is no single national rulebook for Corps lakes. Each project office publishes its own set of regulations covering: launch permit requirements, area closures, horsepower limits, waterskiing and wakeboarding rules, camping on Corps land, and seasonal restrictions. These are published at 36 CFR Part 327 as the baseline federal regulation, with project-specific rules issued as supplements. Find the project office website for the specific lake before you go.
• Launch permits are required at most Corps lakes. Many Corps projects charge a launch fee or require a seasonal launch permit. Parking your trailer at the ramp without a valid permit on display is a citable offense. Day permits and annual passes are typically available at self-service fee stations at the ramp or online through recreation.gov.
• State boating law applies on Corps lakes in addition to Corps rules. State registration, state PFD requirements, and state speed rules all continue to apply on Corps-managed water. Corps regulations add to state law; they don't replace it. Enforcement on a Corps lake can come from Corps rangers, state conservation officers, or both.

• 400+ Corps lakes nationwide. Baseline regulation: 36 CFR Part 327. Project-specific supplements govern per-lake rules. Find the project office website before launching on an unfamiliar Corps lake.
• Launch permits: most Corps projects require a day permit or annual pass. Self-service fee station at the ramp or recreation.gov. No permit displayed = citable.
• State boating law applies in addition to Corps rules, not instead of it. Enforcement by Corps rangers and/or state officers.
• Per-project rules cover: area closures, horsepower limits, tow sports zones, camping on Corps land, seasonal restrictions.

• Bureau of Reclamation reservoirs are concentrated in 17 western states. BOR built reservoirs primarily for irrigation and water supply; recreational access is managed through partnerships with state agencies and concessionaires. Lake Mead, Lake Powell, and Shasta Lake are all BOR waters. Rules are administered through the National Park Service at NPS-managed BOR units, or through state parks agencies at others.
• Tennessee Valley Authority (TVA) operates 49 dams on the Tennessee River system. TVA reservoirs (including Norris Lake, Chickamauga, and Guntersville) are managed directly by TVA for power generation, flood control, and navigation, with recreation as an additional use. TVA publishes reservoir-specific boating rules, including no-wake zones around dams, restricted areas near navigation structures, and seasonal recreation closures. TVA rules are separate from state boating law and supplement it.
• Dam exclusion zones are strictly enforced on all BOR and TVA waters. Both BOR and TVA maintain restricted areas around dam structures, hydroelectric intake facilities, and navigation locks. These zones are marked by buoys and signage. Entering a dam exclusion zone is a federal offense and is actively enforced by on-water patrols. The exclusion zone begins significantly upstream of the visible dam face, not at the concrete structure itself.

• BOR: 17 western states. Recreational management through NPS (for NPS-managed BOR units) or state parks agencies. Find the specific managing entity for the reservoir you're using.
• TVA: 49 dams on the Tennessee River system. TVA publishes per-reservoir boating rules at tva.com; supplement state boating law. No-wake zones near dams, restricted areas near navigation structures.
• Dam exclusion zones: federal offense to enter. Marked by buoys beginning significantly upstream of the dam structure. Actively enforced by on-water patrols on all BOR and TVA waters.

• Federal recreation passes cover many launch fees. The America the Beautiful Annual Pass (also called the Interagency Pass) covers entrance fees at many federal recreation areas, including some Corps lakes and BOR facilities managed through the NPS. It does not cover all launch fees; some Corps project fees are separate and not covered by the pass. Verify for your specific lake before assuming the pass covers the launch.
• Annual permits are often better value than day passes for regular users. Most Corps projects offer annual launch passes at a significant discount over purchasing daily passes. If you launch on the same lake more than a few times a year, the annual pass typically pays for itself in two or three uses.
• Permits must be displayed where visible from outside the vehicle. The permit or pass must be on the dashboard, affixed to the rearview mirror, or otherwise visible from outside the vehicle. Keeping it in the glove box does not satisfy the display requirement. Corps rangers ticket based on visible display, not whether you have the permit.

• America the Beautiful Pass covers entrance fees at many NPS-managed BOR units and some Corps facilities; does not cover all Corps launch fees. Verify per-project.
• Annual vs day pass: annual pass typically pays off in 2-3 uses on frequently visited Corps lakes.
• Display requirement: visible from outside the vehicle (dashboard or mirror). Glove box does not satisfy. Corps rangers cite on visibility, not possession.

• Water releases from hydroelectric dams create sudden, dangerous current changes. Below dams, water can rise several feet in minutes when generators are operating. The current below a dam is not a calm river; it is engineered turbulence. The restricted zone below a dam exists because releases are unannounced to the public (though sirens or lights may warn if you're close enough to hear or see them). Stay out of the exclusion zone and well away from tailwaters during any power generation period.
• Reservoir levels change with operational management, not just rainfall. A Corps or TVA reservoir may drop 20 feet or more during a managed drawdown for maintenance, flood control pre-positioning, or dam inspection. Submerged hazards (stump fields, road beds, bridge abutments) that are always below water at full pool become live propeller hazards during a drawdown. Check current pool elevation through the managing agency's website before launching.
• Fluctuating levels affect ramp usability. A ramp that works well at full pool may be too shallow, too steep, or inaccessible during low pool. Many Corps and TVA projects have seasonal ramp closures tied to pool elevation. Check which ramps are open before trailering to the lake.

• Below-dam tailwater: unannounced hydroelectric releases create sudden current surges. Stay out of exclusion zones and tailwater areas at all times, not just during visible generation.
• Managed drawdowns: pool can drop 10-20+ ft. Stump fields, road beds, bridge abutments become active hazards. Check current pool elevation at managing agency website before launching.
• Ramp usability tied to pool elevation: seasonal ramp closures common at low pool on Corps and TVA projects. Verify open ramps before trailering.

• Federal reservoir agencies overlay state invasive species rules with their own requirements. Some Corps and BOR reservoirs in western states have mandatory watercraft inspection programs independent of (or supplementing) state programs. Where a federal reservoir is in a state with a mandatory inspection law, both the state law and the reservoir's own program apply, and they may have different decontamination standards or inspection station locations.
• Mussel-fouled vessels may be denied launch at federal reservoirs. Corps and BOR reservoirs in mussel-sensitive areas (particularly the Colorado River basin and other western regions) may refuse to allow launch of a vessel found to carry mussel larvae, adults, or veliger contamination. Mussel inspection certification from a recent inspection may be required at the launch ramp. Check the project office's current requirements before trailering to the ramp.
• TVA manages invasive species in its reservoir system separately. TVA tracks invasive aquatic species in the Tennessee Valley reservoir system and coordinates with Tennessee, Alabama, Georgia, Mississippi, North Carolina, Virginia, and Kentucky agencies. TVA's reservoir-specific pages list known invasive species presence and any applicable inspection or decontamination requirements for each reservoir.
• Clean-Drain-Dry applies as the baseline on all federal reservoirs. Remove all aquatic vegetation, drain all bilge water, live wells, bait wells, and ballast before leaving any federal reservoir. Dry the vessel thoroughly before the next launch. Many project offices post inspection reminder signage at ramps. Check it on arrival.

• Corps/BOR western reservoirs: federal inspection requirements may exist in addition to state law. Different decontamination standards or station locations are possible. Check the project office before you arrive.
• Launch denial: mussel-positive vessels may be refused launch at Colorado River basin and other western reservoirs. Mussel inspection certification required at some ramps. Check project requirements before trailering.
• TVA: reservoir-specific invasive species tracking and requirements per TVA's reservoir pages. Coordinates with the state agencies in the Tennessee Valley.
• Baseline: Clean-Drain-Dry on all federal reservoirs. Remove vegetation, drain all water systems, dry before next launch.
