Wisbech Town FC’s derby at Holbeach was postponed due to a waterlogged pitch on a rain-lashed Easter Monday to forget.
This leaves the Fenmen tenth in the UCL Premier Division table and they host 12th-spot Harborough Town next Saturday.
The local derby clash between March Town and Ely City, the first time in a few years this fixture has been played, went ahead and beat the weather.
The promotion chasing Robins, who were on a three-match unbeaten run, were on top from the first whistle.
Goals from the visitors came in the seventh and 27th minute. Ely hung on to seal the win.
This leaves March in 12th spot in Thurlow Nunn League Division One and Ely third.
