Most 水ways in 马里恩 County are part of The Upper White River Watershed which encompasses a 2,720平方英里的面积(大约. 1.700万英亩)在印第安纳州中部. The Upper White River Watershed extends across sixteen (16) counties including significant portions of Hancock, 马里恩, 亨德里克斯, 约翰逊, 汉密尔顿, 摩根, 布恩, 蒂普敦, 麦迪逊, 亨利, 特拉华州, 和兰多夫县, 还有欧文的一小部分, 梦露, 布朗县和克林顿县.
The Upper White River Watershed is broken down in 马里恩 County into smaller sub-水sheds: Eagle Creek, 降低落溪, 上瀑布溪/盖斯特水库, 愉快的流水——白河, 白舔溪,鹅Creek-White河, 弯曲的Creek-White河, 以及清溪白河. The extreme eastern and southeastern corner of马里恩Countyis in the Driftwood River Watershed which is broken down into the Grassy Creek,巴克溪和小糖溪的流域. 分水岭 are also known by their Hydrologic Unit Code or HUC.
“Children learn about their place in the world—their street address, 城市, 在很小的时候就有了邮政编码. But there is another important dimension to our lives that is also important to our sense of place — our 水shed or ecological address. The future of the planet and the protection of the nation’s 水 resources depend on a universal understanding and appreciation of 水sheds”.
“每个人——不管我们是不是住在农场, 在一个城市, 或者住在海边，住在分水岭上, 我们都对它的健康产生影响. 有些分水岭很小，只排出几英亩的土地. Others, such as the Chesapeake Bay, are expansive estuaries where the rivers meet the sea. And then there’s the Mississippi River 水shed which feeds the nation’s fertile cropland and drains two-thirds of the United States before emptying into the Gulf of Mexico. 分水岭 supply drinking 水, provide recreation and respite, and sustain life.”
“The first step to creating and sustaining healthy and livable communities is understanding one’s place in the big global picture. 孩子们可以简单地掌握这个, 在很小的时候就有了强大的概念, but it needs to be universally embraced by all citizens to make a lasting change in our world and our environment for today’s and future generations.”

降雨期间水流过陆地的情况, 它可以携带肥料, 松散的土壤, litter and other pollutants into streams and other surrounding 水 bodies. 作为一个结果, everything we do on the land affects the quality and quantity of our 水 resources and the natural systems that surround us. 因此, the natural resources and the quality of life in our communities are directly affected—positively or negatively—by the way we plan for and manage the land we use.
Community 水shed management planning is a way to consider a wide range of environmental, 经济, and social issues along with the community’s vision for the future of the 水shed under a single framework. Working within physical boundaries rather than political boundaries, the 水shed management planning process provides opportunities to address 水 quality and habitat issues beyond the scope of single jurisdictions. 它提供了一种确保环境保护的手段, 支持生活质量问题, and accommodates 经济 development using the 水shed as the planning framework. Any kind of planning allows you to put a single action into the context of a larger vision—水shed management planning allows for that vision to include healthy natural resources and 水ways.
Local governments and 水shed associations play an essential role in restoring 马里恩 County’s 水 resources through the restoration and protection of local 水 bodies and habitat. Many local agencies are becoming more engaged in 水shed management planning. Because these entities have developed an understanding of the connection between land use and environmental health, it is hoped that 水shed planning will become an integral part of comprehensive land use planning within their jurisdictions. Localities in the 马里恩 County area have begun to conduct 水shed management planning in areas such as Eagle Creek, 降低落溪 and the 上瀑布溪/盖斯特水库 分水岭.
