The Dalton boat ramp provides access to the Connecticut River in northern New Hampshire's Coos County. This location sits on a major river system—the Connecticut is the longest river in New England at over 409 miles—making it an excellent choice for paddlers and boaters seeking substantial water. The river at this point is in its upper reaches, still relatively close to its headwaters with significant elevation drop ahead.
Paddlers should be prepared for the river's substantial flow and current. The Connecticut River averages over 22,800 cubic feet per second of flow with an average velocity of 5+ feet per second, indicating strong current conditions. The gradient through this region averages 6.5 feet per mile, typical of northern New England river sections. This ramp is best suited for experienced paddlers comfortable with moving water, and conditions can vary significantly with seasonal runoff and weather. Check current water levels and weather conditions before launching, and always wear appropriate safety gear.
