An alternative to beat the summer heat and to enjoy some great fishing is to fish at night.  The night has other advantages such as generally less wind and no skiers or Jet Skis.  A little breeze is still preferred especially on those hot humid stale nights.

Fishing under the lights has been around forever.  Most folks who live on the water have lights on their docks that attract fish.  I have used a lantern, hanging it off of the edge of the boat to do the same thing. 

Many folks believe that the lights attract bugs (and they do) and the fish move in to feed on the bugs. Yes some of the fish do feed on the bugs, but in reality it is usually the plankton that are attracted to the light, which then brings in the small fish and then the bigger fish. 

The night lights available these days come in a variety of colors, but most agree that green lights are generally the best.  Science will tell you that the most penetrating frequencies of light in the water are blue and green in the spectrum of available colors.  White lights are still offered and they do work, as white has all the colors of the spectrum. However, the general consensus is green is all that you need.  Some folks may disagree.  

Most of all the newer lights and some of the older lights are submersible.  The big advantage to submersible lights is the fact that the bugs are kept at bay.  Very little light is reflected up, which cuts down on the bugs.  You know and I know that the bugs can get unbearable from a hanging white light. 

The action can be tremendous under lights.  Concentrating the baitfish will bring in the predators and at times the action will be outstanding especially if the fish are in a feeding frenzy.  Many indoor fishing docks across the country use lights to attract fish.  It is a known technique.  

There are many different portable lights on the market, but there are four types I am aware of.  They include floating sealed beam lights, fluorescent lights, LED lights and submersible halogen lights.  All of these types of lights will do the job.  There are pros and cons to each of them. 

Light Emitting Diodes (LED) are lights that generally have the longest life and use the least amount of energy.  They used to be priced out of the market, but currently the prices are competitive with other types of lights.

Many of these types of lights will run the night on a few dry cell batteries. LED-type lights come in a variety of colors and can be configured in many different ways.  Those that I have seen are configured in a submersible vertical tube.

Submersible halogen lights operate under the surface so there is minimal impact due to wind and waves and you of course minimize the bug impact with the light under the water.  These halogen lights will generally draw more current for the same level of lighting as fluorescents, but they are generally smaller and you can buy replacement bulbs.

When night fishing on a boat with lights, it is a good idea to anchor the boat securely so that movement is minimized.  The floating lights you choose can be placed right next to the boat.  The other submersible type lights can be lowered to a desired depth around the boat.

Wait a few minutes and the baitfish will move in.  The bigger predators will more than likely be under or on the edge.  Be careful not to spook the predators.  Work different depths until you locate the best depth.  If for some reason the fish don’t move in, move and find another potential spot. 



Lake Granbury water temperatures are in the low to middle 90s. Water is hot. This last weekend the thermocline was around 15 to 20 feet down. White bass (sand bass) are fair to good on slabs on shallow flats and humps typically in 10 to 15 feet of water.  Striped bass are good to 10 pounds on live bait fished near creek ledges near DeCordova and Indian Harbor.  Largemouth bass are good to excellent on crank baits and soft plastics fished near main lake points and deeper docks later in the day. Crappies are fair to good on minnow and jigs suspended near deeper structure. Catfish are good to excellent on cut shad fished on flats and humps adjacent to the river/creek channels on many areas of the lake.  


On other lakes, Lake Whitney striper fishing is hit and miss in the heat.  Some good catches reported above the Katy bridge on feeding flats.  Look for surface action on Whitney under the white cranes midlake.  Lake Proctor sand bass limits are common.
