In Order to Track the Flow of Water from Any Point in the Watershed to the Creek, a Map

Huron Creek Storm Water Distribution Prepared by Brian Grieve Fall 2006 CE 4905 Introduction:

In order to track the flow of water from any point in the commercial and residential areas of the watershed to the creek, a map of the flow has been constructed. It is important to know how water is entering the creek. Due to the large amount of impermeable surface, water can quickly travel to the creek during rainfall events. This can cause large spikes in the flow of into the creek. This water can transport large amounts sediment and contaminants into the creek. If they are being transported into the creek, the map can aid in finding out where in the watershed they are coming from.

Methods:

The information gathered to make the map came from interviews with public officials, plans from state agencies, observations from topographic maps, and visual inspection. GPS coordinates were taken for each inlet and outlet that carries water into the creek. Dimensions of all of these inlets and outlets were measured and recorded. Pictures of each inlet and outlet were also taken. Using information from public officials, plans from state agencies, and topographic maps were used to determine where different areas of the watershed are drained to.

Results:

There are two maps that contain the storm drain information. The first map (stormwater slide2) shows where all of the inlets and outlets are located. It also labels each of the inlets and outlets. The second map (stormwater slide1) outlines which groups of inlets drain to each of the outlets. Each shaded area is connected to a specific outlet by one or more lines. Then the map (stormwater slide1) shows the path the water takes from the outlets to the creek if necessary. These paths do not show the exact path the storm water takes. They are just there to make it easier to visualize the path that the storm water takes. The map should be shown to a member of the Houghton City Public Works to confirm the size of the areas on this map. Each shaded area and path is assigned a code. There are two excel sheets. The first (descriptions sheet1) contains all of the information on each of the inlets and outlets. It has the GPS coordinates, dimensions, descriptions, and a link that will bring up a photo of the inlet or outlet. The second excel sheet (descriptions sheet2) has the paths that the storm water will take. It contains all of the information needed to decipher the second storm water map. References:
