The Canal & River Trust's income has increased by almost £5m to a total of £210m, the charity’s accounts for the year to 31 March 2019 show.
The charity’s income was up from £204.9m the previous year, according to the accounts.
Expenditure was at £201m, compared with £198.2m the previous year, meaning the charity made net income of £9m before investments.
The charity spent £156m on charitable activities, including record spending on its waterway operations, maintenance and repair.
The value of its property investments also ballooned, from £692.6m to £758.7m.
About 60 per cent of the Canal & River Trust’s income is from commercial sources, with 2.5 per cent from donations. The charity said that more than three-quarters of its total funding was from "low-risk, steady income sources".
The number of donors increased by 29 per cent, the charity said, and volunteers gave 671,000 hours of work to the trust over the year.
The highest earner at the charity was paid between £220,001 and £230,000, a slight increase on the previous year.
Allan Leighton, chair of the Canal & River Trust, said: "This year we have maintained the investment in the network that is so vital to all our four million regular users – boaters, anglers and towpath visitors – while taking the decision to reposition the trust to raise awareness of the hugely important role that waterways are playing in improving the daily lives of millions of people.
"As we look towards the 2020s, we know that the foundation we have laid in this first phase of the trust’s life will give us a strong platform from which to build a powerful case for ongoing funding and a compelling appeal to a broader audience to make their lives better by water."
