About ten years ago, the city had a very nicely designed kayak/canoe/stand-up paddle board, hand carry launch ramp built on the Winnipesaukee River, opposite Sawyer's Jewelry, and I've never seen anyone use it?
It's just below the Avery Dam and close to the big intersection of Main St and Union Ave, or Routes 106 and 107.
Depending on time of year, dam outflow volume, and water temperature, the river is good fishing and very clean. About five different low clearance road over-passes or bridges cross over the run from the Avery Dam for 1 1/4 miles down to huge Lake Winnisquam, making a lot of the river unaccessable to many motor boats that will not fit under the low bridges.
Could be worth a look see for the local paddler looking for someplace new to explore ....... an urban river with old stone wall style embankments in the downtown, and earthen natural embankments just downstream from the downtown area.
www.downtowngymlaconia.com just recently opened, opposite the kayak launch ramp, so's maybe some of the athletically inclined may want to go hit the river on a sup ..... maybe sup yoga ..... and do that downward dog moving down river with the natural river flow .... you be paddl'n down dat river on a sup ..... low bridge ahead ..... got to kneel down to fit under dat bridge dere...... you be paddl'n down dat dere inner city lazy Winnipesaukee River ......mak'n some waves ...... yo!
