Anyone know of a map or data set that would help us figure out which storm drains end up in Lake Hiawatha?
See below.

Dear neighbors,
I have been removing a lot of trash from Lake Hiawatha since early spring. In my effort to clean the lake I became discouraged that after every rain event, new trash arrives. I performed a little experiment. I placed a marked, colored ball in the gutter at our residence and lo and behold, I found it in the lake two weeks later, after a rainstorm. It was found right next to the big storm sewer egress on the north side of the lake. see attached photo. We live at 41st street and 23rd ave. s. I have since watched this storm drain/culvert and seen loads of debris and trash come into the lake after each rainstorm.
So... the trash in our streets is going directly into the lake. it floats out and some settles to the bottom, others drift to the shore. plastic bags, cellophane, snack wrappers, plastic bottles, cans, etc. I don't know the extent of the drain system, how far it extends or if this is even the way the system is supposed to work. I also have safely removed a lot of disturbing items such as diapers, syringes and condoms from the water and the lake shore. I thought you would want to know about this. People are eating the fish and children are swimming at the beach, wildlife makes its home there, and it's a stop for an amazing variety of migratory birds. Can we fix this?
Something we each can do immediately, is to monitor the street gutters in front of our own residences for trash. it could make a difference.
There is no screen or anything on the storm sewer egress/culvert at the lake. I have notified the city, the parks and the MCWD of my observations. it hasn't been very long so I'm still awaiting responses. I suggested in my letters that it might be possible to create a vegetation barrier in the lake and/or put a filtering cage/coarse screen near the mouth of the culvert. This could be a way to at least catch some of the plastic etc. I am willing to help in anyway i can, and I bet many of you are too.
I've removed 37 bags of trash from the lake and shore so far- conservatively estimating about 30 lbs. per bag, that's over 1000 lbs. total! There are decades of accumulated trash on the shore and the task of cleaning the lake is far from complete. Incidentally, The Minnehaha Creek Watershed District is having a clean up on 7/26/2015 for the whole watershed, this includes Lake Hiawatha and the creek. Here is the link if you want to help them out: http://www.minnehahacreek.org/events/2015-minnehaha-creek-cleanup-july-26
Thanks for letting me share my observations with you.

A storm sewer (storm water) drainage data project took place back in 2010: http://metrogis.org/projects/stormsewers.aspx - Not sure where the effort went after that. The study they link to here:
Suggests to me that local subsurface drainage needs to be added to the National Hydrography Dataset (NHD), which is already very complex. It's possible that Mpls has their stormwater drains mapped out but they don't have it posted on their open data site.
Sorry this isn't a complete picture, but perhaps it will lead to more.

I am not sure where this came from, but this was posted:
Btw, this a great reminder about how neighborhood forums be they on E-Dem, Facebook, etc. are a great source of demand and use cases for what civic tech can do:
