Next DLC meeting will be March 16. Interlaken Townhall, 100 Grasmere Ave at 7PM

The DLC was chartered in 1974 by the 7 shore line towns. Our mission is to provide leadership, guidance, and resources to preserve and restore Deal Lake and its tributaries as a healthy and stable ecosystem. In addition, control lake levels during heavy storms to the best of our ability with limited ocean tide controls.

    Considering Landscaping or Building by the Lake?

    Deal Lake, its tributaries and watershed are regulated by Federal and State agencies. Check before you dig.
    Typically any land 50 ft adjacent to the Deal Lake shoreline is strictly regulated by NJDEP regulations. You may need a permit to do work.

    At a minimum, the NJDEP regulatory personnel recommend that a property owner file for a Jurisdictional Determination in advance of initiating any work adjacent to the shore line. Click here for general info

    Lake Lowering Protocol: 8/14/2013

    Commission Receives Authority to Manage Lake Level

    Annually, the Deal Lake Commission receives a lake lowering permit from the NJ DEP.  The objective of this permit is to minimize the risk of property flooding and protect fish and wild life by managing the lake level prior to a rain event greater than 1 inch.  NOTE:  Coastal flood warnings apply to all low lying Lake Residents and even a lake lowering may not prevent property damage due to tidal surges and rain within the watershed.

    Lake Lowering 

    Lake Lowering Presentation by J. Toher/S. Souza – 4/18/2019

    Experience has shown that no two rain events are the same and there are many factors that must be considered before determining when to open the gates and when to close the gates.  The factors include:

    If, after taking all these factors into consideration, it is determined the expected rain event has potential for property “structure” flooding , the DLC chairman or his designee will call one of at least three trained operators to open one or both flume gates to facilitate the draw down.  Each sluice gate (North/South) can lower the lake by ½ inch per hour.  Operators have full authority to open gates if a Flash Flood alert is issued.

    Currently, Deal Lake can handle a 1 inch rainstorm with no lowering of the lake from its normal height of about 2 inches above the dam height.  A minimum of two commissioners are aware of the weather forecast at all times.   Special attention is taken to any local forecast that calls for coastal flooding and heavy rains predicted for our area.  These responsible parties determine if the lake needs to be lowered as a precautionary measure prior to, during, or after a rain event.

    Rain events between 1 and 2 inches Deal Lake will be taken down to about 2 inches below dam height prior to the rain event.  Based on past experience there is no need to “drain the lake for these events.  The lake shoreline is covered at this height to protect fish and wildlife and the enjoyment of boaters and others that use the lake..Rain events predicted above 2 inches in a 24 hour period will cause rapid rise in the lake, thus proactive measures to lower the lake below the dam height will take place well prior to the storm arrival and during.   A map showing flooding potential from various rain events can be found on te DLC web site.

    Gate Closing

    The gates will be closed when the lake level has dropped to where the risk of flooding has been minimized,  high tides will adversely affect the lake, or has met the DEP lowering limit of 12 inches below dam height.

    Flume opening and closings can be followed on twitter or via our web site:
