Notice to Reservoir Users – Boating Requirements at Tulloch Reservoir

To maintain the integrity of the Aquatic Invasive Species (AIS) Prevention Program and ensure compliance with established protocols, all vessel banding and inspections must be performed only by entities formally approved and authorized by Tri-Dam.

All vessel launching on Tulloch Reservoir must occur exclusively through designated launch sites authorized under the AIS Prevention Program. In alignment with current AIS protocols, launching from private properties or any unauthorized locations is strictly prohibited.

We appreciate your continued cooperation in helping safeguard Tulloch Reservoir.

• All motorized vessels must arrive Clean, Drained, and Dry.
• Motorized water vessels must launch from Tri-Dam approved facilities 
• Requires screening of all trailered water vessels and must adhere to program requirements (see Banding requirements below).
  • To ensure your vessel is properly recorded and eligible for launch, please request a text or digital receipt confirming that your band has been entered into the national database.  
• California Boater Card is required for anyone operating a vessel.
• All watercraft launched in Tulloch Reservoir must display a current Tri-Dam  sticker or have an issued day pass.  This is in addition to the State Department of Motor Vehicles (DMV) sticker that is proof of the State's mussel fee payment.

Banding Acceptance

Banding Requirements:

• Only Tulloch 30-day quarantine bands as well as re-entry Tulloch bands, that can be verified in the national banding database will be honored
  • 30-Day or Re-entry bands from other waterbodies are not accepted at this time

Approved Decontamination Reciprocity – New Melones to Tulloch

Boaters may take their vessels to New Melones to complete an approved decontamination. Once decontaminated, a band will be issued, and vessels may proceed to Tulloch Reservoir for same-day entry. A valid decontamination completed at New Melones will be honored at Tulloch. Please be sure to call ahead to confirm availability of decontamination services. Additionally, ensure your vessel is properly recorded and eligible for launch in the national database by requesting a text or digital receipt at the time of service.

This is a one-way agreement and applies to decontamination only. A 30-day quarantine band or re-entry band from New Melones does not qualify for entry at Tulloch.
