Hatlem Pond was dredged in 2014 and has been filling in with accumulated sediment, as expected. The questions that are before us today are: how much has it filled in since the dredge and what is the fill rate? The Glen Lake Association Board of Directors has created a four member task force to look into the future of Hatlem Creek and pond and are monitoring the situation.
In the coming weeks, Spicer Engineering, Inc. will once again –this will be the third time –visit the pond and take depth measurements at specific points throughout the bottom. These data points will help us determine how much and how fast the pond is filling up with sediment. It will take $5,700 to cover the costs of the field work, along with the data calculations and extrapolations as to when the Hatlem Pond may need dredging again in the future.
Also, Hatlem Pond dam will undergo repairs and improvements under the direction and supervision of Spicer Engineering, Inc. and updates of the completed work in this important area will be shared in the near future.
Finally, some shorelanders are reporting sediment build-up on the bottom of the shoals inside the “blue line.” This sediment build-up may be due to a few factors that are at this point, only speculation. It is unclear if the new, larger culvert on County Road 675 is playing a role in unimpeded sediment transport. Additionally, the winds, or lack thereof, are not “flushing” the sediment off the shoals in the early to late spring season and weak lake-wide currents are slowing down the process of sediment dispersal.
