A half-and-half sky over the water today, with stillness over the whole water with the glass slipping lower. Fish at Grass Lake should hold close to the margins and the shelf beyond them. Set the alarm around the night. Change depth before you change anything else. Falling temperatures are switching fish back on.

You will find Grass Lake in Mason County, Michigan. Height above sea level is 741 feet. Small at around 6 acres: two anglers spread out cover most of it. On size it sits at the modest end of our Mason County list. Scottville lies 10 miles from the water. For a city, Grand Rapids is 80 miles off. Others worth noting: Lake Meade 0.6 miles away, Chancellor Lake about 0.7 miles, Alma Lake 1.1 miles away, Williams Lake about 1.3 miles and Gun Lake 1.4 miles away. This one is safely inside the county line.
Nothing in our records gives a depth for this one. This is a lake, so the margins and the first drop matter most. On a natural lake the weed line and the shelf beyond it do the work. Public occurrence data for Mason County names rainbow smelt, alewife, bloater, yellow perch and johnny darter. Those are county-wide records, so not every one of them will be in this water. The shape of Grass Lake rewards a slow walk along one bank.
The seasonal spread runs 21°F to 69°F. Hard water is a season in its own right here. Firm cover through the cold months, then open water from early April. Averages suggest open water from about early April through to roughly mid December. Spring is short and heavy here; autumn is longer and steadier. Grass Lake runs to its own calendar within the local pattern.
There is no clear statement anywhere on who can fish it. Access points are not mapped for this water, which suits people who like quiet. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Check locally before you travel, because a wasted drive is a long one. Some stretches are reserved and marked as such on the ground. Lake Meade, 0.6 miles away, makes the obvious fallback. What applies at Grass Lake may have changed since it was mapped.
