FISHING GUIDE · SINALOA BASS LAKES, MEXICO

Lake Baccarac and Lake Comedero (Sinaloa, Mexico) Fishing Guide

Baccarac and Comedero are remote Sinaloa reservoirs known for big Florida-strain largemouth bass, fished almost entirely through lodges that handle pickup, boats, guides and permits. Most trips are mainly catch and release, and lake levels drop with drought and seasonal water releases. Sinaloa is under a U.S. 'Do Not Travel' advisory, so read the current advisory before you book.

📍 Sinaloa, Mexico, in the foothills of the Sierra Madre. Lake Baccarac is the reservoir behind Bacurato Dam (Presa Gustavo Díaz Ordaz) on the Río Sinaloa, about 90 miles east of Los Mochis.
