Leonard’s Gage is currently operational.

The Leonard’s Gage is an US Geological Service operated flow and temperature gage (i.e. gauge) on the Namekagon River near the Leonard’s School Road crossing, located about 4 miles (downstream) of Cable, Wisconsin. The Namekagon River is part of the St. Croix National Scenic Riverway, a unit of the National Park Service. It was set aside to protect its outstandingly remarkable ecological, recreational, and other resource values. Unfortunately, there is no one source of funding to cover the cost of operating Leonard’s Gage, which is currently $13,000 a year. We are very pleased to announce that the St. Croix River Association (SCRA) has secured an agreement with the National Park Service and US Geological Service, working through Bayfield County, to continue operations of this gage for the next 3-5 years.

Leonard’s Gage has been in place since 1996 and its continued operation is important for both scientific and recreational reasons. The gage provides important information to scientists on flow and temperature; particularly important to understanding and planning for variations brought on by climate change. The gage also provides important trip planning information for recreational paddlers, fishermen, and outfitters. During high river flows, the information provided by Leonard’s Gage is important to public safety. Take a look at

St. Croix River Association (
The SCRA mission is to protect, restore, and celebrate the St. Croix River and its watershed. SCRA is committed to taking sustainable action now so that future generations can enjoy the St. Croix National Scenic Riverway, where water is clean, scenic vistas remain, and open space for habitat, sustainable farmlands, and healthy tributaries co-exist with thriving communities. Wild and scenic rivers, with the aquatic diversity such as that of the St. Croix and Namekagon Rivers, are a truly rare resource. Working together we can ensure the next generation will have a chance to visit, and in turn value, our area’s national treasure.

Looking Forward
Please know that NRP is committed to continuing this gage, and we look forward to working with you, and organizations such as Trout Unlimited, the Izaak Walton League, Bayfield County, the National Park Service, and the St. Croix River Association to ensure that this important gage stays operational. All Leonard’s Gage donations that we receive will be forwarded to US Geological Services via SCRA. Thank you for your on-going support.
