View map of the River Stour below (click on image to enlarge):
The Environment Agency (EA) is the navigation authority for the section of the Stour that runs from Brundon Mill (upstream of Sudbury) to Cattawade (near Manningtree). Through navigation is possible for all types of craft from Sudbury to Great Henny, travelling through Great Cornard Lock. Lighter craft, such as canoes and kayaks, can be portaged between Great Henny and Stratford St Mary. Larger, manually propelled craft can travel from Stratford St Mary to Brantham using the locks at Dedham and Flatford.

Craft Registration – All craft must be registered to take to the water on any part of the Inland Waterway network of England (canals, rivers, navigations). There are a number of ways that this can be achieved:
- You can register your craft annually with the Environment Agency or obtain a short term/visitor registration. Visit the ‘At Home & Leisure’ section of their website – www.environment-agency.gov.uk
- You can join Canoe England (part of the British Canoe Union) – annual membership permits your craft on all navigations in England and provides Civil Liability Insurance amongst other benefits – www.canoe-england.org.uk/membership

Leptospirosis (Weil’s Disease)
It is important that all river users are familiar with the symptoms of this infection, which are similar to those of influenza (temperature, muscle aches and nausea). Leptospira bacteria is often carried by rats and excreted in their urine, which contaminates the waterways. Infection is more likely in slow-moving or stagnant water in areas where agriculture and rodents mix but exposure can be heightened through some activities e.g. angling where minor cuts and nicks are common; or swimming where some water will almost inevitably enter the mouth.
Precautions:
- Be aware that activities that can cause open wounds or that take place near the water’s edge where rat urine is more likely to be found increase the risk of contracting the disease.
- Do not swallow river water
- Avoid capsize drill or rolling in stagnant or slow moving water
- Wash your hands before eating
- Cover minor scratches, cuts and abrasions on exposed parts of the body with waterproof plasters
- Where possible, wash or shower after taking part in water sports and riverside activities
- Consult your doctor if you feel ill after coming into contact with water anywhere near or in the river.
