There are five creeks in Niagara on the Lake that flow into Lake Ontario. This 2012 report card on the conditions and water quality of the creeks is the most recent report from the Niagara Peninsula Conservation Authority.

Friends of One Mile Creek and two other local groups in NOTL sent a letter to the Town on Monday raising concerns about the potential for flooding from a construction project that involves excavating most of a four-acre site to build two levels of underground parking. The construction is for the planned Two Sisters Resort at 325 Kng St. – the site of the former Parliament Oak elementary school.​

A group of neighbourhood volunteers has created a pollinator garden at the entrance to the Heritage Trail at Paffard and Charlotte Streets, on the upper reaches of One Mile Creek.

With all the discussion by federal and provincial governments about investment in infrastructure, Friends of One Mile Creek (FOMC) wants to increase the discussion about how green infrastructure can play a vital role in Niagara on the Lake through beneficial socio-economic and environmental assets.

The Niagara Peninsula Conservation Authority (NPCA) in summer 2021 conduxted forest and stream rehabilitation at the Two Mile Creek Conservation Area. THe area is accessed at the end of Butler Street and from the Garrison Village neighbourhood.
