Nibi Metrics

Real-time water levels, forecasts, and alerts for lakes and rivers across Canada and the US. Built on official government data.

Nibi Metrics turns raw gauge readings from official hydrometric networks into something a person standing on a dock can actually use: is the water high or low for today, which way is it moving, and how unusual is this? This page explains where every number on the platform comes from and what we do to it along the way.

Water Stories

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.

Jump Creek at the Mouth Water Level

Live river level, flow, historical records and forecast for Jump Creek at the Mouth in Canada, BC, Canada, built from official government gauge data.

About Jump Creek at the Mouth

Jump Creek - a lively waterway at the edge of the wilderness.

Jump Creek at the Mouth slices through the rugged landscape of South Central Vancouver Island, offering a glimpse into a vibrant aquatic ecosystem. The creek lies within a drainage area of approximately 59.5 square kilometres, collecting rain and melted snow from the surrounding highlands. These waters contribute to the dynamic hydrology of the region, which is heavily influenced by seasonal changes.

The watershed context

The South Central Vancouver Island watershed is characterized by its mountain hydrology, where runoff from spring snowmelt typically peaks between May and July. This seasonal freshet helps to maintain water levels, making rivers like Jump Creek a crucial lifeline for local flora and fauna. Nearby peers such as Ash River, Browns River, and Carnation Creek highlight the interconnected nature of these waterways, illustrating a rich tapestry of hydrology where each stream plays a role within the broader ecosystem.

Local rivers often reflect the influence of glaciers during warmer months, sustaining flows even as summer progresses and evaporation begins to take its toll. These patterns are critical for sustaining biodiversity and managing the ecological health of the area.

Why the data matters here

Understanding the flow of Jump Creek is vital for local communities and wildlife alike. Discharge measurements are available from the station, assisting in monitoring water levels and informing conservation efforts across the landscape.

As of today, Jump Creek's reading can be compared against the historical median for this calendar day, which has been recorded over 49 years by the Water Survey of Canada. This ensures a reliable context for understanding current conditions and highlights how today’s flow stands relative to typical annual patterns. This comparison serves as an important benchmark, allowing residents and stakeholders to make informed decisions regarding land use, conservation, and recreation in this vibrant watershed.

How this page is built

Readings come from official government gauges and are rolled into daily records: the daily mean, high and low for every day on record. Each calendar day gets its own baseline from the full history, so the level you see is compared against what this specific date usually looks like rather than an annual average.
