Reel in Michigan's Fisheries, January 2017 edition
This quarterly publication is an outreach item to Michigan anglers to describe what the DNR's Fisheries Division does and why we do it. Specifically it strives to highlight the work Fisheries Division employees are accomplishing on inland lakes and streams. Reel in Michigan's Fisheries will often showcase waters that are actively managed and provide the public with enhanced knowledge and the opportunity to access the wealth of information contained in survey reviews and management reports.

Climate change effects on Michigan's fisheries
Climate, the long-term pattern of temperature and precipitation, varies greatly from the Upper Peninsula to southern Michigan. This variation in climate creates differences in water temperatures and stream flows across the state which in turn influences where different fish species live, how well they reproduce and grow, and the types of fisheries we see around the state.
Effects of dams on fish populations in Michigan
Dams are constructed for a variety of reasons. Historically, many were built for water power to run mills. Later, many of these same mill dams were used for things like hydropower. Other dams were built for reasons such as navigation, recreation, lake level control, or aesthetics.
Figuring out how to fish Douglas Lake in Cheboygan County
One of the largest lakes in Michigan is also one that has very little fishing pressure. A hidden gem of sorts, Douglas Lake in Cheboygan County is almost 3,400 acres in size and has a maximum depth of 80 feet. It is located near Pellston ("Ice Box of the North") and has limited public access as much of the land surrounding it is privately owned.
The importance of connectivity of Michigan's rivers & streams
Creeks, streams and rivers flow throughout Michigan's many landscapes. On their path from upland areas to the Great Lakes, these waters encounter different types of structures that block or interrupt the movement of not only the water itself, but also the aquatic organisms that live in these waters rivers. These blockages can cause problems for the organisms that live in the streams and are often referred to as "connectivity issues".
Investments to increase DNR's fish rearing capacity
Big changes are coming to the Department of Natural Resources' Little Manistee River Weir and Thompson State Fish Hatchery thanks to the renovation support provided by the Michigan Legislature and Governor Snyder in the fiscal year 2017-18 budget. The total investment is estimated at more than $12 million.
