Base view: the Cache la Poudre is highlighted on the street map; fishing-condition modeling covers all reaches west of I‑25. Temperature/CFS overlays apply to your fishing scope west of I‑25.

Color is based on a reach-level estimate using nearby mainstem gauge readings. Tap the river for the current estimate.

The dashboard requests upstream and downstream mainstem flowlines from the USGS Network Linked Data Index, starting at the Fort Collins gauge.

Temperature confidence
A measured temperature controls only the nearby river reach. The rest stays yellow unless enough temperature observations exist to support a conservative range entirely below or above 65°F. This avoids pretending one downstream sensor describes the whole river.

Combining stream gauges and Gateway weather…
Flow: upper-canyon reaches use the Gateway water-balance anchor; in-town reaches blend Gateway, Fort Collins, and Timnath flow anchors with uncertainty for diversions, imports, storage, and ungauged tributaries.Temperature: canyon reaches use Gateway weather plus upstream cooling; Fort Collins reaches blend Gateway and Fort Collins weather. Confidence remains low until more direct water-temperature observations are available.

Fishing-condition values west of I‑25 combine measured flow anchors with modeled reach estimates; modeled values are not direct observations.
