Great time last week, volunteering with @RiverThameCT on Sheep Brook. Fed by #groundwater from the Chalk #aquifer, it's a tributary of the Lewknor Brook. Before & after removing small rock weir to improve fish passage & enable natural flows to reshape channel & gravel bed

Why the sad face☹️ Yesterday, on the dry bed of #River Thames at Ashton Keynes, 7 miles from its source. Repeat of August 2022 when I looked hopefully upstream at same location. The result of exceptionally low #groundwater level in #Cotswolds #aquifer after prolonged dry weather

Out on the #water, paddling down the River Kennet earlier this week. Despite the prolonged dry weather, it's looking good because of natural #groundwater flows from aquifers across the catchment and #river management.
