GREAT LAKES-ST LAWRENCE RIVER WATER LEVEL BULLETINS


USACE Six-Month Water Levels Forecast Bulletin

A monthly graphical bulletin produced by the U.S. Army Corps of Engineers consisting of the current water levels for the Great Lakes as well as a six-month future forecast of water levels. Both the water level network used to compute the current water levels and the six-month forecast of water levels are coordinated under the auspices of the Coordinating Committee.

Fisheries and Oceans Canada Monthly Water Level Bulletin

A monthly graphical bulletin produced by Fisheries and Oceans Canada consisting of the current coordinated water levels of the Great Lakes as well as a coordinated six month future forecast of water levels. Both the water level network used to compute the current water levels and the six-month forecast of water levels are coordinated under the auspices of the Coordinating Committee.

Environment and Climate Change Canada – LEVELnews

A monthly publication produced by Environment and Climate Change Canada providing an update on Great Lakes – St. Lawrence River water levels. This publication is dependent on water levels and outflows coordinated under the auspices of the Coordinating Committee.

USACE Weekly Great Lakes Water Level Update

A weekly update produced by the U.S. Army Corps of Engineers discussing weather conditions, Great Lakes water levels and outflows from each of the Great Lakes. The water levels and outflows are coordinated under the auspices of the Coordinating Committee.

USACE Water Level News and Information

A monthly update produced by the U.S. Army Corps of Engineers discussing the current outflow strategy for Lake Superior, monthly narrative summaries of Great Lakes water levels and related information of interest. This publication is dependent on water levels and outflows coordinated under the auspices of the Coordinating Committee.


USACE Great Lakes Water Level Outlook

A periodic 12 month outlook on Great Lakes water levels produced by the U.S. Army Corps of Engineers. This product is an educational supplement to the USACE six-month forecast. It is based on water level and hydrologic data coordinated under the auspices of the Coordinating Committee.

GREAT LAKES-ST LAWRENCE RIVER CLIMATE BULLETINS


Great Lakes Climate Quarterly

A quarterly publication providing a narrative summary of the climatic and water level conditions in the Great Lakes Basin based in input from a number of partner agencies in Canada and the United States. Information on water levels and flows in this publication is coordinated under the auspices of the Coordinating Committee.

NORTH AMERICAN PRECIPITATION


Bi-national Precipitation Analysis

Canadian Precipitation Analysis (CaPA)
The Regional Deterministic Precipitation Analysis (RDPA) configuration of the Canadian Precipitation Analysis (CaPa) is a near real-time gridded precipitation product provided by Environment and Climate Change Canada (ECCC). The grid has a resolution of approximately 10 km and the domain covers all of North America (Canada, USA and Mexico). It uses gauge data, radar reflectivity and GOES imagery to modify a trial field provided by the GEM numerical weather prediction model using an automated statistical interpolation technique.

Multi-sensor Precipitation Estimate (MPE)
Hydro-meteorologists at the National Weather Service’s (NWS’s) 13 River Forecast Centers (RFCs) utilize the Multi-sensor Precipitation Estimator (MPE) to produce rainfall estimates that cover the 48 contiguous United States as well as portions of Canada and Mexico. Data from many sources are manually analyzed at the RFCs to produce the day’s best precipitation estimate on a 4 km grid on a 1 hour time step.

Merged CaPA and MPE
The “Merged” dataset is created using both the Canadian Precipitation Analysis (CaPA) and the Multi-sensor Precipitation Estimate (MPE) datasets. Outside of the contiguous 48 United States, the CaPA data is copied as it is. Within the contiguous 48 states, the MPE data is resampled to match CaPA’s cellsize, and then copied. Within 10 km of the boundary of the contiguous 48 states, and over the Great Lakes, the data from CaPA and MPE are combined and interpolated.
