How this recommendation was formed

Each hour is evaluated independently. A NO-GO condition takes precedence; otherwise an unresolved required input produces Unavailable, cautions produce GO · Caution, and an hour with none of those conditions is GO.

NO-GO

At least one blocking safety condition is present.

  • A relevant blocking NWS alert, forecast thunderstorm, or known official closure or restriction.
  • River conditions reach a location-specific high-water boundary or a rapid rise makes the available forecast guidance unsafe.
  • Sustained wind above 15 mph, gusts above 20 mph, or visibility below 1 mile.
  • The conservative water-temperature lower bound is below 60°F.

GO · Caution

No blocking condition is present, but at least one caution applies.

  • Sustained wind from 10 mph or gusts from 15 mph up to their NO-GO boundaries.
  • The representative water temperature is below 65°F.
  • High-water caution, relevant caution-level alerts, fog or reduced visibility, or elevated runoff.

Unavailable

No known NO-GO condition is present, but the model cannot responsibly resolve the hour.

  • Required alert, river, water-temperature, wind, or gust evidence is missing, expired, or too uncertain for that forecast horizon.
  • A known blocking condition still remains NO-GO even when another required input is unavailable.

GO

Required evidence resolves the hour and no blocking condition or caution is present.

  • GO describes the modeled weather-and-water hour; it is not a guarantee and does not replace checking official restrictions at launch time.

How forecast hours are handled

  • The outlook contains up to 72 separate hourly decisions, so the result can change from one hour to the next.
  • Hydrology requirements become more conservative farther into the outlook and use official forecasts or National Water Model guidance only where the configured river reference is compatible.
  • Temperature proxy distance remains part of the uncertainty range. The pooled Fox River cooling allowance is added only while the observed 24-hour temperature trend is cooling.
  • Temperature uncertainty crossing 65°F alone does not create caution; the representative temperature controls caution, while the conservative lower bound protects the 60°F NO-GO threshold.

Forecast

Mon, Sep 14 66–66°F Mostly cloudy 9% rain · wind to 15 mph
Tue, Sep 15 (Today) 66–80°F Mostly cloudy becoming chance showers and thunderstorms 81% rain · wind to 15 mph
Wed, Sep 16 (Tomorrow) 62–72°F Slight chance showers and thunderstorms becoming chance showers and thunderstorms 61% rain · wind to 10 mph
Thu, Sep 17 67–79°F Slight chance showers and thunderstorms becoming showers and thunderstorms likely 62% rain · wind to 5 mph

Local Water

About North Batavia Pool

The local water body represented by these measurements and forecasts.

North Batavia Pool is the Fox River impoundment between Geneva Dam upstream and North Batavia Dam downstream.

Conditions shown here describe this specific reach. Provisional modeled discharge, literal recent changes, upstream water-temperature context, and a dedicated local weather forecast provide the available current information.

No direct continuous mainstem discharge gauge or local river-level measurement represents the pool. The displayed flow is a modeled estimate and is labeled as such.

For detailed river access, landmarks, portages, and navigation information, see the printable maps from Fabulous Fox Water Trail.

About these public conditions

River discharge is a provisional modeled estimate, while weather uses a dedicated National Weather Service forecast. No local stage, depth, velocity, or dam-hydraulic inference is presented. Current facts remain separate from the explicitly labeled On the Water recommendation, and no seasonal or historical interpretation is presented.

  • USGS observations are provisional and may be revised.
  • Conditions can vary within a pool, especially near dams, tributaries, bridges, and constrictions.
  • Flow is a provisional modeled estimate for this reach, not a direct local gauge reading.
  • A representative local stage reading is not available for this reach.
  • Water temperature is observed at the regional Fox River near McHenry station; local water temperature can differ.

Definitions: Flow is discharge in cubic feet per second. Stage is gage height at a specific station. The 24-hour direction compares the current reading with the prior reading: positive is rising or warming, negative is falling or cooling, and zero is steady. Detailed numeric readings and recent traces are available under Current River Data below.
