• Where to Fish on Kostal Reservoir

  Depth here is unknown, so count the lead down before committing. A soft bed grows weed late into autumn, which keeps fish shallow. Weed, then depth: that is the order to fish a water of this kind. On Kostal Reservoir that means starting tight and working out. Fish move up in low light and drop back as it brightens.

• Seasonal Patterns

  July runs about 75°F on average, January about 23°F. Winter shuts the surface down for months. Firm cover through the cold months, then open water from mid March. The open-water window runs from around mid March to about mid December in an average year. May into June fishes hardest, and September gives a second good stretch before the lid returns. Anyone fishing Kostal Reservoir regularly works to that calendar.
