LureScore index · 2026-10-29
The score combines air temperature, pressure level and stability, wind, rain, season and a short-range trend trigger. It is a timing aid — not a fish finder.

Estimated water temperature · 2026-10-29
15.2 °C, most likely between 12.0 and 18.4 °C (about 54–65 °F). A modelled estimate for the water around Des Moines on 2026-10-29, not a gauge reading.
Built from the last 7 days of daily mean air temperature (weighted toward recent days), a seasonal phase term, and coefficients fitted against 55 USGS gauges across 171,799 daily records; leave-one-station-out error is 1.96 °C. Large reservoir releases, spring-fed reaches, deep pools and tidal water can sit well outside this range. Water temperature tells you how actively fish are likely to feed — it does not tell you where they are. How this estimate works →

Saylorville Lake above Des Moines produces walleye and white bass that respond to stable pressure fronts, while the river through town holds channel cats that feed most actively around rising water. The table above recomputes the index for each of the next seven days from that day's forecast, so you can time an outing to the strongest window instead of fishing the calendar.
Autumn brings cooling water and aggressive feeding ahead of winter — often the most consistent index readings of the year.
Windows are scored on the same model as the daily index. Sunrise and sunset edges are built into the schedule; the strongest mornings usually follow a stable or improving pressure trend.
The waters around Des Moines include Des Moines River and Saylorville Lake. Saylorville Lake above Des Moines produces walleye and white bass that respond to stable pressure fronts, while the river through town holds channel cats that feed most actively around rising water. Start with public access points on these systems, check local regs, and let the daily index above guide timing.
The usual targets are Walleye, Channel catfish and White bass in and around Des Moines. Seasonal timing shifts the bite — the forecast table on this page is computed for the same weather signals that matter for these species.
Yes — a Iowa state fishing license is required for anglers 16 and older (saltwater and freshwater endorsements may differ). Buy one through the Iowa state wildlife or natural-resources agency before you fish.
The index recommends the strongest windows printed under today's score — typically the low-light morning and evening windows. Sunrise and sunset edges are almost always worth more casts than midday, especially in the warmer months.
