COUNTY PERMIT REQUIRED FOR ANY SHORELAND ALTERATION PROJECT
It has come to the attention of the TMLA Board of Directors that
many shoreland property owners are not aware of the need for a County Permit for
any shoreline protection efforts such as rip-rap. The State Department of
Natural Resources (DNR) has authority over the water in the lakes up to the
ordinary high-water level.
Their literature describing shoreline renovation
states that no State permit is required for rip-rap projects that project no
more than 10 feet into the water. However, the County has authority for the
land above the ordinary high-water level, and the County does require submission
and approval of a permit application.
Please see the latest information about DNR Permits on the DNR Website.
Permit application forms and information can be obtained from
the Cass County Department of Environmental Services (P.O. Box 3000, Walker, MN
56484); Tel.: 218-547-7241 or 1-888-547-3301, Ext. 241 - speak to John Sumption
or Dave Kaufman). You must submit a plan of your renovation project along with a
drawing, and pay a fee of $130.00. For ordinary rip-rap projects the County will
grant permission routinely.

UPDATED: Water Level Report
WATER LEVEL REPORT by Tom Cox, Chair, Lake Level Management Committee
Birch Lake Outlet Structure Update
On July 18, DNR staff from St. Paul and Bemidji, representatives from Birch,
Pleasant and Ten Mile Lakes, Stan Kumpula of the Cass Board of Water and Soil
Resources and Jim Dowson, County Commissioner, met in Hackensack to discuss the
procedure for obtaining an amended or new DNR permit for the management of the
Birch Lake Outlet Structure. With the advice of David Ford, Supervisor, Surface
hydrology Unit, DNR Central Office, St. Paul, and Kirk English, DNR Area
Hydrologist, Bemidji, reached a consensus involving permanent placement of a
four-inch log in the outlet structure for a period of up to two years, during
which time volunteers would make twice-weekly readings of the water levels on
the three lakes and report them to the DNR. Under Mr. Ford's guidance, the DNR
will use this data, along with precipitation and river and ground water flow
data, to determine the character of a fixed wier to be established at the
current outlet structure's location. The Ten Mile Water Level Committee
anticipates that the DNR's study, supported by Cass County's own concurrent
hydrological study of the Upper Boy River (being supervised by Stan Kumpula with
the assistance of John Alden), may result in a new outlet structure that will
address both the low water concerns of Birch Lake residents, and the high water
concerns of those who have homes on Ten Mile and Pleasant Lakes and along the
Boy River in Hackensack.
Water Level Statistics
|Historic Data, 1973-2000
|Avg Level, '73-'00:
|Summer 2001 Readings
||1380.22' (new high of record)
Walt Kane reports that on September 14, Ten Mile was four tenths of an inch
higher than on the same date a year ago. Also on September 14, the water was
down 5.2 inches from it's May 1 level, and down 9.36 inches from it's peak on
June 14, when it reached 1380.22, the highest level on record since the DNR
began keeping records in 1973. But the lake was up 1.2" from its level on
last November 1. Also of interest, from June 25, when the stop log was removed,
until July 30, when it was reinstalled, Ten Mile's level dropped 4.3 inches.
It's impossible to tell how much of this drop was due to the absence of the stop
log and how much was due to July's long, hot, dry spell. Walt Kane calculated,
however, that during this same 35-day period in other years of record, Ten Mile
rose, on average, 1.3 inches.
