THE EARL LAKE LEGACY PROJECT

Hello I'm Zoltan, and Earl Lake in Howell Michigan is impaired. We have formed a NOT for profit group the earl lake restoration and maintenance group. We Have had many scientific studies shown our lake is on the decline. Our community around the lake has gone into action and we have a beautiful plan to fix the lake. if you want to know more keep reading and watch the videos. EITHER WAY PLEASE DONATE, AND SHARE THIS PAGE

OUR SCIENTIFIC STUDIES CONCLUSION:

Conclusions

Earl Lake is a typical eutrophic lake based on the limited data I have seen so far- it is stratified

and has anoxia (no dissolved oxygen) on the bottom which is a detrimental aspect of the lake.

Anoxia

prevents fish access to cool bottom waters as refuge and for food for cool water species especially, but more importantly anoxia allows a chemical reaction to occur that releases large quantities of

phosphorus and ammonia (we expect the water quality data to show this when we get it) which is

termed **INTERNAL LOADING**. These nutrients are mixed into the lake on fall and spring overturn which are then used by algae and macrophytes to grow profusely, resulting in large costs to control them in the

lake. The second problem is the high concentrations of chlorides. On the first trip on the lake, I

measured chlorides to be 220 mg/L and I also measured chlorides some years earlier and those samples were even more dramatic, ranging from 270 to 800 mg/L which are outrageously high values.

The conductivity was also high & gt; 1,000 uS at some stations. So far, Daphnia, which are susceptible to high

chloride concentrations appear to be present, so they are not all extirpated, providing some hope that

the lake is still hanging on ecologically. Note that chlorides are chemically and biologically inert so they

can only be changed by dilution or evaporation. I have not had much experience with limnological

solutions to this problem. I have some references I will read over and see if there are any solutions, but

I would be surprised if there are any. Obviously if the inputs to the lake were curtailed, eventually rain

and water from outside would dilute the concentrations to more reasonable levels.

INTERNAL LOADING: refers to the release of nutrients, such as phosphorus and nitrogen, from the sediments at the bottom of a lake. In the case of an island lake, internal loading occurs when nutrients are released from the sediments within the lake itself, rather than being introduced from external sources like rivers or streams. This can happen due to natural processes or human activities, such as excessive nutrient runoff from surrounding land or the accumulation of organic matter in the lake over time. The release of nutrients from internal loading can lead to water quality issues, such as algal blooms and decreased oxygen levels, impacting the overall health of the lake ecosystem.

The funding: Will be going to mechanically weed harvesting the lake pending permits. This is done WITHOUT the use of chemicals. we will ONLY be harvesting agreed upon areas, shorelines, etc.
