The river's shallowest water will be located on the inside bends and in the straightaways between bends. Because the current is relatively slow on inside bends, sand and fine gravel will deposit here to form a soft, shallow bar. Riffles will often be found in the straightaways, where the river gurgles over shallow rocks. On smaller rivers, bars and riffles create hazards for boaters and access for wading anglers. The best place for a wading angler to cross a small river is diagonally through the straightaway, from inside bend to inside bend. However, make a few casts before crossing; fish often prowl riffles and bars for minnows and crayfish, especially in periods of low light. The downstream end of the riffle, where it plunges into the next deep hole, is also a good fish location.
