Bass Fishing At Obregon - Lake Oviachic

If you like to catch lots of big bass, this is a great place to visit. It has a reputation of delivering plenty of four to six pound bass virtually any time of the year. While this lake is not turning out monster bass, ten pounders are not uncommon. For the most part, the fishing is focused on shallow water. At times the fish will be on structure in deeper water.

Swamped Boat on Oviachic

This needs to be a major lesson learned. Please don’t ever attempt to cross this dangerous basin when windy without having some contact to a buddy who can help if needed. Always pack extra water and food because these issues wouldn’t ever had happened if they would have waited until the wind let up or waited until morning to come in. Obviously it is impossible to toe a boat in these waves so don’t try it; you might be able to toe it with the waves to safety behind 3 sisters. If we wouldn’t have had someone to help get these fishermen to safety we would be talking about even more serious issues. These were about 5 ft waves at 5pm and they were mean but at 6:30pm when I came in they were laid down and easy to come in.

Travel Warnings

Any time you travel outside the USA, be aware that you are subject to local law governing the area you are to visit. As a general rule, travel to lakes in Mexico is considered safe. However, there are reports of unrest and violence between competing drug cartels, and Mexico law enforcement. Most of this activity in confined to areas away from the bass fishing lakes. Some of the border towns and population centers in Mexico experience higher than normal levels of crime and violence. Often, American border town information centers can advise regarding cartel activity in neighboring Mexico border towns. It is always best to caravan, stay on the main highways and be aware of what's going on around you.
