The soar is not currently high at all, though of course that can change quite quickly. Plan to do hops between more stable mooring places, so Kegworth, zouch, anywhere between bishops meadow lock and pillings flood lock, (Loughborough is a decent town for shops, pubs, laundrette and market on thursday/Saturday. Services at the basin but personally I would then go under chain Bridge and moor on the wide towpath stretch, rather than the basin. From there , there is a cut through to aodi, b&q etc. Nice very peaceful mooring just outside Loughborough, just before miloars Bridge. Above Barrow deep, above Mountsorrel lock (can flood), Sileby has a boatyard and services, but not a place to be in flood. Then above junction lock, another small boatyard and chandlery as you turn off the wreake towards syston. Moorings by watermead are fine , anywhere along that stretch to the weir. Birstall has moorings near the village, though I've heard there have been some hassles there, never experienced a problem myself, pubs shops, takeaways. Then off you head to Leicester with 2 secure mooring options.
When the river comes up it soon drops again. Lived on it some 16 years, only ever had one major "eeeek" moment.
Beautiful river.
