The P.E.I. Liberals are promising to give watershed groups more money to help their work improving rivers and streams.

Leader Robert Ghiz announced earlier this week his party would increase the funding to $1 million each year for the next four years, up from $800,000 annually.

"It's a significant difference," Mark Bishop, vice-chair of the P.E.I. Watershed Alliance, told CBC News Tuesday.

"Watershed groups have always been limited by resources, and not by work to do, you know, or willingness to do it. So, yeah, it will make a difference. We'll just keep our fingers crossed and hope that this goes through."

The money would be split amongst 30 existing watershed groups. Provincial grants are usually announced in May.

Earlier this month watershed groups complained they were not getting as much money as they expected from funding set aside from a new beverage container deposit program.
