Making plans for summer getaways with family and friends? Add fishing to your list. Plan a day trip or bring along fishing gear on your next weekend or camping trip.
The best fishing is early in the morning or later in the evening and after dark. Like anglers, fish adjust to the heat. “Fish will move to deep water to cool off during the brightest, hottest part of the day,” said Joe Larscheid, chief of the Iowa Department of Natural Resources Fisheries Bureau.
Look for fish in the outside edge of weed beds or structure, near shade during the day. Find underwater structure such as brush piles or rock reefs within a lake with the interactive fishing atlas or fish structure maps on the DNR website at http://www.iowadnr.gov/Fishing/Fishing-Maps.
Fish often are suspended in deeper water, just above the thermocline – a midsummer phenomenon many lakes develop creating two layers. Below the thermocline, often 8 to 10 or 12 feet deep, oxygen is nearly nonexistent. Many fish suspend just above the thermocline, where the water is cooler.
“Bluegills may spawn several times in the summer,” advises Larscheid. Look for them in traditional spawning areas in shallow water. “If you are not successful in these areas, try drift fishing in deep water (15-20 feet).”
Largemouth bass and channel catfish will be close to shore. Look for bass near cover; stumps, wood structure. “Bass and bluegills will use vegetation for cover and shade. It also holds a variety of zooplankton and insects which attract baitfish.”
“The white bass and wiper bite gets hot when the water heats up,” said Larscheid. “Hot weather is also a good time to catch big channel catfish and largemouth bass.”
White bass are active in the summer in the flood control reservoirs (Coralville, Red Rock, Rathbun and Saylorville). Follow the seagulls to spot white bass. Calm days are best because the seagulls can see the shad easier and will be feeding on them. Splashes on the water surface are good signs, too, as the shad leap from the water trying to escape.
