The southeast Minnesota chart is a nearby comparison for northeast Iowa trout streams. Use the warmwater guide for ponds, lakes, and other rivers.

Reference views: Driftless · Warmwater.

Pack from the warmwater field guide and match food on the water. Seasonal trout stocking does not establish which insects will be emerging.

Reference views: Warmwater.

The Smokies chart is a regional comparison for trout fishing. Kentucky tailwaters and warmwater streams need local reports rather than assumed Smokies dates.

Reference views: Appalachians · Warmwater.

Use the freshwater field guide for insect-feeding bass and panfish. Choose flies from the food you observe in the pond, bayou, or lake you plan to fish.

Reference views: Warmwater.

The Penobscot chart is the Maine reference. Northern waters, ponds, and individual river branches may have different ice-out dates and insect communities.

Reference views: Penobscot · Warmwater.

Compare the Pennsylvania chart for trout planning and check western Maryland waters locally. Use the freshwater field guide for bass and panfish; tidal forage is not modeled.

Reference views: Penns Creek · Appalachians · Warmwater.

Start with the Deerfield chart for western Massachusetts river fishing. Ponds, tailwaters, and eastern streams may have different hatches.

Reference views: Deerfield · Penobscot · Warmwater.

The North Branch Au Sable chart includes Hex and brown drakes. Treat it as a river reference; Great Lakes tributary fish runs and lake hatches need a separate check.

Reference views: Au Sable, MI · Driftless · Warmwater.

Use the Minnesota DNR chart for southeast trout streams. Northern lakes and streams differ; the Michigan chart is only a neighboring comparison.

Reference views: Driftless · Au Sable, MI · Warmwater.

Use the freshwater field guide to build a bass or panfish box. Check the shoreline and feeding activity rather than relying on a trout-river calendar.

Reference views: Warmwater.

The White River chart is an Arkansas comparison for Ozark trout fishing. Missouri spring branches, trout parks, and warmwater rivers need local timing checks.

Reference views: White River · Warmwater.

The Gallatin chart is the main reference. Spring creeks, tailwaters, and rivers east of the mountains can have different timing and water conditions.

Reference views: Rockies · Black Hills · Warmwater.

Start with the freshwater field guide. The Black Hills chart is a neighboring South Dakota comparison, not a schedule for Nebraska trout streams.

Reference views: Warmwater · Black Hills.

The Truckee reference is the first river comparison. Nevada stillwaters and desert tailwaters need their own food and timing check.

Reference views: Sierra · San Juan · Warmwater.

Compare the Penobscot and Deerfield references, then check the elevation and river locally. Neither chart is a statewide New Hampshire forecast.

Reference views: Penobscot · Deerfield · Warmwater.

Use the Catskill or Pennsylvania chart as a neighboring trout-river comparison. Check New Jersey stream conditions and use the field guide for warmwater fishing.

Reference views: Catskills · Penns Creek · Warmwater.

The San Juan reference describes tailwater food seasons. Mountain freestone streams and reservoirs should be checked separately.

Reference views: San Juan · South Platte · Warmwater.

Start with the Catskill reference. Adirondack waters and Great Lakes tributaries need a local check; the Au Sable option here refers to Michigan, not New York.

Reference views: Catskills · Au Sable, MI · Warmwater.

Use the Smokies and western North Carolina reference for mountain trout planning. Piedmont and coastal freshwater fishing call for the warmwater guide.

Reference views: Appalachians · Warmwater.

Use the freshwater field guide first. The Black Hills chart is a South Dakota comparison; it does not establish hatch dates for North Dakota lakes or streams.

Reference views: Warmwater · Black Hills.
