#RODMAN RESERVOIR DRAWDOWN SCHEDULE 2020 FULL#

Unlike the other lakes in this schedule, Lake Winnipesaukee is not purposely drawn down in the fall. Not included in this schedule is Lake Winnipesaukee. On October 30, flows at Lakeport Dam will be increased to refill Opechee Lake, and the level of Winnisquam Lake should begin to rise late in the day on November 1. Therefore, the level of Winnisquam Lake is not expected to drop noticeably until October 19. This year, the lowering of Opechee Lake will begin on October 17, and it will likely take two days to pass the water from Opechee Lake downstream through Winnisquam Lake. However, the drawdowns of Opechee and Winnisquam Lakes, which occur on a two-year interval, last only approximately two weeks.

Generally, lake levels are allowed to return to the normal full pond level in the spring. Drawdowns also give property owners an opportunity to conduct any necessary repairs to their waterfront property, provided they first secure a permit from the NHDES Wetlands Bureau at (603) 271-2147. Lake drawdowns are conducted each fall to reduce winter ice damage to shoreline properties and to reduce spring flooding. However, on Saturday, October 31, a release will be made from Greggs Falls Dam in Goffstown to provide an opportunity for canoeing and kayaking in the Piscataquog River downstream. As a result, NHDES will not be making its normal special releases from Horace Lake and Northwood Lake for downstream recreation this year, but intends to resume them next fall. Because of the drought conditions the state has been experiencing through the summer, the levels of many of these lakes are already a foot or more below full. The depth of drawdown listed above is not from the current level, but is from the normal full pond level. As soon as work all work is complete, the lake level will be allowed to return to full pond. Union Meadows Dam will have a drawdown to facilitate some minor maintenance that needs to be done and to facilitate an inspection of the upstream side of the dam.The values listed above are generally the maximum levels reached, although during any given year the levels reached can be either higher or lower due to weather conditions. These larger lakes generally do not reach their full drawdowns until mid or late March.

The drawdown of Howe Reservoir will start in early September for maintenance work on the dam.

The drawdown of Horace Lake will begin on October 30 this year, which is approximately two weeks later than normal.

This drawdown will start on October 5 and the lake level will be raised to the normal two-foot drawdown level after work on the dam is complete. Grafton Pond will be drawn down 8 feet again this year for a two to three-week period for some minor maintenance of the dam.Concord, NH – The New Hampshire Department of Environmental Services (NHDES) announced today that the annual fall drawdown of the lakes and ponds controlled by dams owned by NHDES will be initiated according to the schedule below.
