Flooding - Spring Rain

[O3H]

Ahhh the Rouge, high class sewage spilled onto the lower elevations

https://www.wxyz.com/news/millions-o...to-rouge-river

The 2-plus million gallons dumped into various parts
of the lower and middle Rouge River in late February,
or the more than 6 million dumped in March ....

As this flows downriver, it meets the Detroit River,
and that’s where we have intakes for the GLWA.
That drinking water is directly affected

SO much for our grand water here in the D. Does ANYONE have a visual map showing these flows, and water areas near the homes, etc. Areas at risk of flooding regularly as we see? Thanks.

As all the public governments go GIS - the maps become available

Keep in mind there is no UBER map of extreme high detail, with FEMA elevation zones and houses -- that is scalable to the entire state.

Two separate problems here.

1. Lake levels: Lake levels vary from year to year. The Great Lakes Survey [[since merged with Coast and Geodetic Survey) used to provide a time graph with lake levels for each of the Great Lakes going back into the 1880s. Not sure what caused the fluctuation, but there was about a five foot variance between lows and highs over time. 1950 was a very low year, while 1952 was a veritable flood. The 1930s and the late 1950s were very low years. There is no "cycle" just random variances. I wonder if that graph is still produced.


2. Clinton River watershed. This is a completely unrelated topic compared to lake levels. Yes, the sanitary sewers need to be segregated from the storm sewers though the idea of combined sewers was an accepted sanitary engineering practice at the time the sewers were developed. Even without the sewers, the Clinton River is often too full or too dry as we cycle through too much or too little rain and snow. I can remember a bad drought my last year in Rochester High School [[56-57) when the wits would write on the bathroom stalls "flush the toilet, Utica needs the water".

Oakland County has had for decades [[50 years) COURT ORDERED lake levels -- meaning flow on the Clinton River is highly, highly controlled.
Spring rise up and Fall draw down are selfish laws for the Lake people .

All tooo often the Clinton Rivers turns into mudville. The water heats up forcing the TAXPAYER paid yearly trout stocking effort to move out of the river, downstream to cooler waters and Lake St Clair. Every year they put trout in [[fish in a barrel concept), rape folks for the license, and the fish leave. About as stupid a taxpayer subsidized plan as there ever was. Been going on for 20 years, put fish, where no fish are, repeat, get fish license money, repeat. Pretty idiotic. Take a hint, the fish don't like it.

Fish and sewage don't mix. Oakland County also created the 12TownsDrain sewage overflow project. BUT taxpayers don't make a fuss, because they are apathetic, and like money being wasted for stupid concepts. There is a reason few people fish at Freedom Hill out of the Red Run Drain.

Sun's out - go get some sewage fish out of the Clinton in MtClemens

Some folks familiar with Google Earth can give this a shot :

Multiple reasons for this situation.

A few random thoughts...

Drain tiles on farmland. This land used to absorb and hold the rainwater, but now it flows into the tiles and into the nearest drain, creek, etc. almost immediately. That's a lot of runoff in a short period of time.

One of the biggest areas that drain into the Great Lakes is the huge area south of James/Hudson Bay that drains into Lake Superior. If that area gets heavy snowfall, the Great Lakes will get a lot of runoff, eventually.

Parking lots and roofs - those old fields now drain very quickly into the storm drain system.

We'll be glad here in Las Vegas to take any extra water you might have off'n your hands. Lake Mead is steady this spring but expected to drop a bit more during the summer.
