Michigan Blue Ribbon Trout Streams

***NOTE: This layer is no longer actively used by the Michigan DNR. It has been replaced by the inland trout and salmon regulations layer. The inland trout and salmon regulations dataset provides a more complete overview of the state’s trout rivers. The blue ribbon trout stream data is now for historical reference only*** Michigan is blessed with an abundance of cold, quality trout waters offering 38,000 plus miles of rivers and streams, including over 12,500 miles of classified trout streams. Remarkably, 868 miles are considered premier top-quality streams, which Michigan classifies as its Blue Ribbon Trout Streams (BRTS). A Blue Ribbon Trout Stream must meet certain standards or criteria. It must be one of Michigan's best trout streams, be able to support excellent stocks of wild resident trout, have the physical characteristics to permit fly casting but be shallow enough to wade, produce diverse insect life and good fly hatches, have earned a reputation for providing an excellent (quality) trout fishing experience, and have excellent water quality. Management of Blue Ribbon Streams by the Michigan Department of Natural Resources is directed toward accommodating the needs of trout anglers, maintaining strong stocks of wild resident trout that best suit the character of each stream, maintaining and enhancing trout habitat and the natural stream environment, providing adequate public access and public frontage, and preparing appropriate informational materials on these special Blue Ribbon Trout Streams of Michigan.

***注：密歇根州自然资源部（Michigan DNR）已不再主动维护该地理信息系统（Geographic Information System，GIS）图层，其已被内陆鳟鱼与鲑鱼监管图层替代。内陆鳟鱼与鲑鱼监管数据集可更全面地呈现该州鳟鱼河流的整体情况。蓝带鳟鱼溪流数据目前仅作历史参考用途。***

密歇根州坐拥丰富优质的冷水鳟鱼栖息水域，境内河流与溪流总长超38000英里，其中经分类认证的鳟鱼溪流总长逾12500英里。尤为亮眼的是，其中868英里河段被评为顶级优质溪流，密歇根州将其归类为蓝带鳟鱼溪流（Blue Ribbon Trout Streams，BRTS）。

蓝带鳟鱼溪流需满足一系列标准与要求：须为密歇根州顶尖鳟鱼溪流之一，能够维持健康的野生本土鳟鱼种群，具备支持飞蝇钓抛投的水文条件且水深适宜涉水作业，拥有多样的水生昆虫种群与优质的飞蝇孵化环境，凭借卓越的高品质鳟鱼垂钓体验获得广泛行业口碑，且水质优良。

密歇根州自然资源部对蓝带鳟鱼溪流的管理工作围绕以下目标展开：适配鳟鱼垂钓者的使用需求，维持契合各溪流自然特质的健壮野生本土鳟鱼种群，保护并改善鳟鱼栖息地与溪流原生生态环境，提供充足的公共通行通道与沿岸公共开放区域，同时针对密歇根州这些特殊的蓝带鳟鱼溪流编制配套的科普宣传资料。
